Above, Andrew Stacey mentions that some of the counter-examples in algebra were moved to the nLab. Another candidate, that could perhaps be also somewhat fitting subjectwise, could be the tricki (incidentally created on suggestion of or even by Gowers).
ps: this is explictly not a contribution to the dicussion whether or not this should be considered at all.
]]>Is it possible for the thread to be moved to Tim's blog? I have not asked him if he would accept that, but would do so if movement is possible and there is general agreement with my position. The thread itself, unlike most "big list" threads, contains so much useful information that I cannot bring myself to vote to delete even if I want it off MO.
]]>Thank you for your remarks on my meta contribution. In my opinion your remarks related to anonymity are interesting and legitimate. For this subject however I would really strongly ask everybody to not continue this subject in this thread. I have nothing against this being discussed, after thinking about it for a while I might even open a thread to this end myself, but please let us not mix this into this discussion.
In any case, I did (so far) not officially vote on this question, and won't.
]]>Back to the starting question: as I said I find it a good big-list question for MO and the quality of the answers stayed solid for quite some time (though I believe there is a negative trend) and it meanwhile really has very many answers, and due to the nature of the subject (my original point under 'semi-seriously' I find it very unlikely if something amazing would be added in five months [for a question asking about something extremely rare this would be different, but it is about something common]).
So, due to its quality it stayed open very long (in my opinion the right measure here is not time, but passages through the frontpage), but now some people including me thought it was perhaps long enough. (In recent month the question was idle, now it resurfaced, chance are if it was not closed it would actually be a more frequent visitor to the frontpage in the weeks to come.) What I wanted to know, and to me is the point of this thread is to know how many people still actively care about this precise question being open.
If a few people or also only one person would have told me something like: "I would really appreciated this question would stay open, because [reason]" and this is somehow credible (the reason would not even have to be overly serious), then I would have said, okay, let us keep it open. (You can check the formulation in my original post is only 'I would prefer' and I meant it like this, it is not that I see any urgent need to close it.) However, during this entire discussion noone said anything to that extent. The closest to this were you stating that you consider it as good if the question occassionally appears on the front-page, which to me is some reason but for this particular question a particularly weak one as it is anyway at the very top of the question list by votes. So, that it can hardly be overlooked by anybody new to the site looking around a bit, and everybody else knows it anyway. So the only point of this could be a reminder for long time users that the question exists. To be honest, I am not sure we need this.
In the very end I howver think that our view on what should be an should not be on MO are not that different.
I am not hostile towards big-list question, I just do not want too many of them; and since you said that you are laso a fan of focused, technical question there seems to be not so much dissent here. Only, what I do not want is some sort of automatism that you seemed to advocate that tells that just because at some point a big-list or soft or related question was not closed right away or for a long time, it will have to stay open indefinetly.
Indeed, if I may say so, if your goal is to keep MO open for such content, I believe your are doing this goal a diservice by insiting on this. Because if the situation were like you suggested I would be much more critical towards such questions at the start. Only because I now that we can still 'pull the plug' later in case things go wrong, I am willing to take more risks at the start.
]]>Now, I said silent majority, you might say it is not silent the votes and view are visible. For the latter, the views, I would really give very little significane to this. If one watches the front page. Often questions with negative vote count have the most views as people look, iassume, what is going on. So going by views one could make an argument for posting pure spam as it gets many views. Okay, this is a short time effect and would not last. But, it is also in some sense clear that old and visible question have many views. If a question has many votes it isclose to the top of the question listing by votes. And, lately I was visiting a couple of SE sites out of pure curiosity how they are run and look. What did I do, I checked some random questions, and then those with most votes. Contributing a view. Yet this/my view is 100% irrelevant (except perhaps for somebody wanting to sell adds); in most cases I cannot even rememeber what the question was about on, say, the cooking site or the english site.
Now, votes is a bit more subtle. Yet, still they way voting works on MO is in my opinion also quite arbitrary. Recently a picture of a cat with a somewhat fitting but not overly informative sentence (a LOL-cat or whatever the precise name of this type of internet-trivia is) was posted as an answer almost at +60 now. I really do not think we should encourage posting animal-pictures on MO although it seems highly appreciated by the community. I also have nothing against the fact that this picture was posted, all I am trying to say is that because occassionally something is appreciated by the community does not mean that when the volume of this type of content would be increased it would still be appreciated. By analogy, if I am at a math conference and a speaker tells a joke, and I find it good, I appreciated it and it can make the talk better or more memorable;a and if I do not find it good I do not mind. If however some conference organizer should make the observation that it seems the most appreciated part of the talks are in fact the jokes, and thus arrives at the conclusion it would be best to invite comedians instead of mathmaticians as speakers that will tell nothing but jokes, then the conference can take place without me the next time.
So, I and I believe not too view others either appreciate or at least do not mind so much the occassional big-list, soft, semi-serious or whatever question. But, it should remain the exception. This is also an argument for sometimes closing an existing one. In a rough sense my goal is to have a constant number of open ones. So either I occassionally endorse to close an old one or I endorse to close each and every new one.
For reasons explained by Francois, I actually think it is better to occassional have a new one (both for new and existing user).
How long exactly any particular big-list question (and the same goes for questions with similar characteristics) should remain open, in my opinion depends on various factors such as appropriateness for the site (examples of courrse much better than say jokes), quality and quantity of the answers (if a list grows slowly one can keep it around for longer than one that explodes, if something stays on topic one can keep it longer than if it degenerates into a collection of loosely related pieces of information dressed up as answers), and finally also how many poeple still actively care about the question being open.
]]>One reason for this frustration is that you state various things as if they were established facts, but that in my opinion are not, sometimes going well beyond the subject matter at hand. This puts me in the position that in some sense I have to write an analysis of all these claims to point out why I beleive they are opinions and not facts or even inaccurate.
To wit, the SO-policy. It took me about half an hour to familiarize myself sufficiently much with the situation on SO and then to write down what I have learned. Now, to me it seems clear that the situation on SO does not at all support the idea of just keeping open big-list questions indefinitely. It would if the questions that are locked--not visible in the title--were open, but they are not; somehow I suspect you overlooked this fact that these question are not open, but in a worse state than being closed, to arrive at your conclusion. So it seems to me the SO-policy actually is not unlike the policy we are discussing. Now, if to you SO-policy is relevant to MO-policy (if it supports your point), I would assume that it stays relevant if it turns out actually not to support your point.
Likewise, and even more drastically, if the only argument against closure you initially made is that there is no policy (under which this closure is justified) and therefore the question cannot/should not be close, then it would seem obvious to me that if there actually is a policy this should be of significant relevance to you. But, you mainly chose to change the subject.
And, I could continue this list, analysing various things you said to Kevin Buzzard and to me. Not to make this sound overly critical; I think it is actual a smart way to discuss, in particular as it puts a significant burden of argumentation on my end, which is a bit time consuming in writing, and then I do not want to bore the meta.MO community at large, with pages full of analysis as to whether it is justified to say that there is opposition towards applied math on meta (where from the context this has to be understood as more so than on main) and so on.
But just one more thing for Question 2144 (not the present one). Already many month before the question was closed comments critical to the question and/or making clear that its closure might be imminent where posted (with many up votes). It is true, the precise point in time when it was closed is somehow arbitrary. However, I do not rememeber this precisely (and was not even active in the earlier times), but from the visible answers it seems, that at the end of 2010 (each time the question reappeared) something critical was said. And then in July 2011 when it reappeared after a long 'sleep' it was evetually closed for real. So, in some sense closure was long overdue and it just was 'forgotten' or not relevant when the question is idling somewhere. Also, I disagree that it is a good question; actually the question is not so bad, though quite subjective, but many answers do not match question but answer something else, which one could also ask, but it was not asked in this question. Finally, there was essentially no opposition to the closure (at least none I noticed or is still visible on the question). The only one was you saying 'Vote not to close.' Now months passed, and still noone of the silent majority you invoced complained by a comment or in any other way.
]]>From my perspective, the main issue is the negative connotation you associate with closing. In the case of big-list questions, the reasons for closing are almost never about the question itself, but about some of the negative side-effects it may inadvertantly generate.
Question 2144 is a good example of this. If I recall correctly, it was closed right after some spammy user kept posting religious propaganda in answer to this question. That was obviously not a judgement on the question.
I personally believe that big-list questions are important for MO. For example, they are very effective at attracting new high-level users to the site. However, I can't ignore their bad sides. I believe it is better to have A regular flow of new big-list questions than to have a long queue of good oldies popping up all the time.
]]>If your actual intent should be to further discuss question 2144, or big-list questions in general, or said policy, I suggest you create a thread to this end. Thank you.
]]>In other words, the rationale behind unwanted questions is not just that the closer doesn't want to see them, it's about what he would like this site to be and to do. Not least, it's about the impression that the site will create upon a famous mathematician, say, who comes here for the first time, not knowing what to expect, possibly slightly sceptical in advance, since after all, this is "just an internet forum".
]]>Second, can someone tell me why it is still necessary to have fights over the closing of big-list questions? If you don't like them, do what I just did: add big-list, soft-question, and mathematics-education to your ignored tags and then select "hide ignored" in your prefs.
]]>I even sketched out a precise scenario under which I would (this was just a suggestion, not the only possibility), and Andrew said something similar.
If somebody gives me a good reason why the question should be open, I will vote to reopen. But what I heard so far is not very convincing; not only but also, as it is often based on assumptions that turn out to be inaccurate.
That being said, at the moment, I too feel this particular discussion is pointless. Sorry for having started it.
]]>In fact, the whole tug-of-war between the hardliners and liberals should be irrelevant, except that the software has a very serious flaw: it doesn't allow for effectively ignoring questions with certain tags. If ignoring a tag had the effect of not seeing questions with at least (or only) that tag at all (instead of just graying them out), the two communities would never have to interact like this. But of course we can't change the software. Is it likely that migrating to SE would remedy this?
]]>François thank you for providing this link; I was unaware of this possibilty. (OT: Is there a clickable option to get there for any question?)
What I always new is that typically one can see this via the revision history if there is one. However, for this question there is none. Of course, I could have created one via making an edit, so that I always knew that I could find out and the 'anonymously' was not meant as 'secretly' or with any particularly negative connotation, but mainly as without giving an explanation or reason; sorry for the poor choice of words.
Gil Kalai, I did not mean the anonymously in the way you perhaps understood it, sorry for any misunderstanding. However, what I would still be curious about (and as you can see I already invested some time to look around there and to understand) is what precisely you had in mind with your comparison with SO.
]]>]]>There is a general misunderstanding of what closing a question is supposed to do. Closing a question prevents new answers to be added, and has absolutely no other effects. (Closed questions are just as visible as open ones, they can be voted on just like open ones, they can be edited just like open ones, and comment threads remain open after closing.) So why would you want to close a question? There are three basic reasons (and multiple variations):
Off-topic questions need to be closed because such questions should not be answered here. In this case, it is better to include a link to a more appropriate resource.
Big list questions need to be closed after the big list has been generated and new list items are unlikely to provide any new insights.
Questions that are too vague, lack context, or otherwise need serious editing should be temporarily closed until appropriate edits are done. This is because answers appearing before the edit are very unlikely to correctly answer the final form of the question, so it is best to prevent such answers from appearing altogether.
Closing of type 1 are permanent; closings of type 2 are permanent but usually occur several months after the question has been posed; closings of type 3 are intended to be temporary, but if the edits are never made they become permanent.
Many are closed or even locked. One (Hidden features of Phyton) is 'only' protected (something we do not have) and has a sort-of 'table of content' in the question. And another one 'Phyton IDE' while seemingly open has a huge warning not to ask something like this, and docuemnts a large amount of work in the question.
So, I did not find anything comparable to the present situation. That is an open question with that many answers where there is no table of content like infomration in the question nor any other information edited into the question that sofar was obtained from the list.
As I said right at the start, in my afterthought, to me it is to a large extent the lack of any overview information that makes it difficult to find this question still being open useful. (I did find it a good question, and I will continue to do so, after all it woud still be visible; only an ever continuing stream of duplicates and semi-on-topic answers is something I do not find useful. [At least the former could be avoided, by this overview information.] And, Andrew said something similar, and Thierry statement is in some sense not that different,
Or, for comparison: recently somebody (I believe David Roberts) suggested to close Proofs without words; Mariano said he would like the question to remain open and said that he pays attention that there is no accumulation of duplicates and not really on-topic answers.
For this question, so far, nobody did or said anything along these lines. Only five users anonymously clicked reopen and you argue mainly abstractly.
Before your last comment not a single person said "I find it useful that the question is open because ..."
]]>So what I would like to see from those who champion the big-list type of question is a little extra effort. Why not take the answers from this question and put them somewhere in a little more organised fashion. Speaking for myself, I'd be happy to see this on the nLab. Then one could order them by topic (for example) and link concepts to explanations on other pages.
When the "counterexamples in algebra" question came up, I did this - though I've failed at keeping it up.
If this were done, and maintained, I would even be happy at keeping these questions open because I would know that someone would be keeping an eye on the thread and ensuring that any new information was put in a more useful place. It would also reduce the number of double posts as a link to the ordered page could be put in the main question with a link "Check to see if your answer is here first". As it would be a page with some system, it would be easier for a potential contributor to see if their answer was already there. Of course, not everyone would check this but some would.
]]>Finally, I do not quite understand why the wish that there should be a good specific reason for closure is in itself in contradiction with the policy or the reasons given by some (including me). For example, having aquired (too) many answers is something specific to a question and of direct practical relevance (as opposed to a policy or reasoning along the lines, after a year a question is automatically closed).
]]>Users are unlikely to carefully read through long lists, which leads to many duplicate answers. (This particular big-list has a large amount of deleted duplicates.)
As time goes on, new list items tend to be more and more detached from the topic. (This particular big-list has been more on-topic than others, but this effect is still perceptible.)
Some big-lists are are inexhaustible (e.g. 1083, 5450). If left open, they would keep coming back to the front page with high frequency, which rapidly gets annoying to regular users. (One could try to make a case that this one is not of this type, but with that many answers...)
]]>Big list questions need to be closed after the big list has been generated and new list items are unlikely to provide any new insights.
It is my opinion that for such a high-profile question it might be better to arive at a consensus or a solution via discussion rather than to send it through various open/close cycles.
My opinion is: It was good it was open for a long time, but now I would prefer if it was/stayed closed.
Here are the reasons.
It seems to me the software is not really made to deal with question with that many answers. I am often on a slow connection with poor harware, it is really difficult to handle this and related questions (on technical grounds).
There is an ever growing risk of duplicate answers and almost duplicates. Which is particularly large as there are only limited ways to structure and or search the answers (for the latter one could use google in a targeted way as a work around, but still); cf. the first point.
Finally, and semi-seriously, if a false belief was not added over that long a time it can't be that common.
Afterthought: In case some should really want to keep it open, one solution I could imagine is that one or a group of these users does for this question what Gil Kalai did/does for Fundamental Examples that is make it so that one can get an overview over the already given answers.
