@Vladimir Dotsenko: Thank you for the reply. First, in retrospect, I should have phrased my first comment differently. Sorry about that. Yet, it was indeed at least also trying to understand your point of view (tough to that end a different phrasing without the provocative touch would have been admittedly more productive). And, sure trying to understand the other person's point of view is important. But, perhaps, if I may say so, since you were so far not active on meta (not sure whether you read it), it might also not have been a bad idea to elaborate on your point of view a bit more. There was nothing to understand, it was a general negative statement.
What I mean is that it is unclear what to you are "questions like this." I can assure you that some people here will understand all five I listed as "questions like this" in this context. Now, after your explanation I/we know that this is in fact not your opinion. Or, when you say that you agree with Ryan that "The reason MO is a success is in part because it has a narrow mission." then it is not clear what this "narrow mission" is in your opinion. The default assumption would be you also share Ryan's opinion on this mission, but from what he tends to say in such discussion I doubt that he will consider 3 of these 5 as fine, and 1 borderline. And which is which? In case at a latter point in time you should have time for further elaboration, I would be interested in it, since your point of view seems not to fall into some of the 'standard categories' on meta-MO and as such would be interesting to have docuemnted in more detail.
Not to take this thread off-topic, I think a somewhat similar purpose could be served if you could say what exactly it is that you dislike about the current question. Say, that it is 'just yet another list' that it is 'subjective' that it is 'possibly controversial' that it 'could influence hiring decisions' that it is 'useless as the information is readily available elesewhere' to paraphrase some of the objections made so far.
ADDED: to my considerable embarssement, I notice that I overlooked one short comment of you yesterday in this thread. This makes some of my assertions irrelevant. However, if it is the subjective and argumentive problem it is not clear to me how this question is so much worse than the less subjective and argumentative of 'qualities of a teacher' and 'a single paper everyone should read', at least one of which you (still) consider as at least borderline. But then perhaps even fine as I guess the one described as a bit on the silly side would be cocktail party.
I was somewhat in favor of the particular question but am in general rather sceptic towards soft/list and alike. The general problem regarding why just blocking categories is no really solution was discussed on occassion. Opinions are a bit mixed. My opinion is that one main problem is the general 'image' of the site and which audience it (thus) attracts.
At the moment one can say to somebody, got to www.mathoverflow.net and have a look at front page to see what it is like. Now, if one would start allowing all kinds of things because properly tag people can block it, one would start to explain if you just see the site it does not look good there is all kind of strange stuff. But if you create an account and then in your profie you need just to add this this this and that tag as ignored; and then have an other look it is about alright. Then this could be a problem.
Also, if there are too many soft questions there is a danger of getting much active audience that is here just for this. This might also cause problems. At the moment, if one does not care about roughly speaking research level math one will rather sooner than later get bored around here and leave, which automatically and non-invasively limits the users group to the intended one.
Finally, soft questions are more likely to cause controversy in various ways. This would also have been a danger for this one (I thought for this one, one could keep this under control, but I can see why others disagree). This controversy than spills over eg to meta and so on.
