But, I admit that my comment was also in part influenced by a (perhaps irrational) feeling of frustration that some seem just not willing to consider using any other site/resource than MO (except if forced to). I think I can rememeber no occassion where somebody said when academia.SE was suggested something like: okay, I will give it a try. I only can remember plenty of, sometimes slightly contrived or even counter-factual, arguments why this definitely is a non-option.

Now, I think I should stop with my mini-rant, since you certainly need no additional convincing regarding this problem.

And, thank you for the final sentence, this was very kind.

A blog is different from a forum. In a blog, the owner of the blog has a lot of control over the discourse and all the other participants can do is comment. Plus, that particular blog seems very quiet, as you point out.

I did not vote to close this question either so far (not to further cultivate my reputation)

Please don't let Hollowdead bully you.

In the AMS's 'defence' there is an AMS blog named 'On the market' (also some others). From a cursory glance it seems not that active; but perhaps this is also since "everybody" asks here rather than there.

And, there is also academia.SE (and contrary to the comment of OP it seems simply not true that this is so PhD students related; perhaps there is relatively more on this, but it is definetly not exclusively on this). Indeed, before the existence of academia.SE I was somewhat welcoming towards such posts, but now I see little reason not to direct them there. (Repost there, close on MO and place a link on MO; to steer the 'traffic' towards there.) Of course, as long as such things are tolerated on MO it could likely (always) stay better or more convenient to ask here and impede or slow-down the development of other activities.

I did not vote to close this question either so far (not to further cultivate my reputation), however the present question in some sense seems rather particularly off-topic. What is the point of disussing on MO the general merits of some other website(s); the MathJobsWiki mainly I assume, though not even this is made clear in the question.

which I think deserves to be discussed here.

I think this is way off topic for MO. I will refrain from voting to close as I can see from this and other examples that there is an incredible pent-up demand for this kind of discussion which doesn't seem to have other outlets. I wish the AMS or a similar organization showed some leadership to create a forum for discussions about the profession. Is there any AMS officer among MO users?
