In light of the generally positive response to this meta-thread, I am creating this to help advertise (and hopefully fully resolve) "interesting" questions on math.SE. I'm not really certain what the guidelines for this should be, but the following are likely uncontroversial:
- Each answer should link directly to a single question on math.SE which has not been sufficiently resolved (and which is answerer believes would be of interest to members of the MO community).
- Each answer should include a short summary of the question asked. There's no need to repost the math.SE question verbatim, but it should be fairly clear what the question is without following the link.
- Feel free to downvote/vote to delete suggestions that aren't "up to snuff". Of course, commentary about why such questions aren't really of interest to the MO community would also be valuable.
- Abusing this thread is an easy way to ensure it is closed/deleted. This thread will stay open only as long as the MO community feels it serves a useful purpose. In particular, don't post links to math.SE question that you know are open problems, and, at the other end of the spectrum, don't post links to math.SE questions that are essentially homework exercises.
(More active MO members should feel free to massage and expand these guidelines to better fit this community's expectations.)
