Pick your battles. Sometimes things don't work out the way I want - maybe an answer is upvoted which I feel doesn't do a great job of answering the question, or one I really like gets a downvote for what I consider a silly reason. Having an edit turned down is no different. A certain amount of response is appropriate - e.g. I think it's fine to add a ...

It is, of course possible, and one does not need a big discussion to start such a project, but one needs to have a clear idea of how the problem can be approached and how to split it into cases/steps/whatever that can be handled by different people in parallel. If we just say "Hey, guys, who wants to think of ABC? Let's do it together!", we'll, most likely, ...

So we put a proposal in the spirit of this idea in here and described in Stack-exchange devoted to research problems, the suggested approaches and updates. The proposal was closed for various reasons. This is in the spirit of Polymath where individual problems are tackled by numerous people. Each post is devoted to a research problem and we post approaches ...

I think previous discussions have covered the ground quite well for this topic, and they should be reviewed. (Hat tip to Martin Sleziak for a link to an excellent starting point.) For ease of reference: there is no exact policy on MathOverflow considering answering off-topic questions. I think a primary reason is that there is some disagreement on what is ...

You don't need a Stackexchange site for this. You can use existing technology to create similar functionality. Suppose I update my user page to include current projects. I can add a section which states open problems I am interested in sharing, along with links I consider relevant. However, I can do more. I can create multiple accounts, each with their ...

Please take note of parallel efforts, usually more narrowly focussed: (1) The Open Problem Garden, originally concentrating on graph theory, but since expanded.           (2) The Open Problems Project, focussed on discrete and computational geometry. This area is under active development through the Workshop on Open Problems and ...

I do not think there is much evidence to support your assertion that your question is specific. You ask whether there is research on "in which mathematical universes does Grothendieck's approach succeed", and we are left with the rather formidable tasks of unpacking the terms "mathematical universes", "Grothendieck's approach", and "succeed". When people ...

I believe that I can give a partial answer to your question. Looking at some of the profiles that you have listed, they seem to be all unregistered users. I used to do something similar (but with only 4-5 names) in 2012, at my beginnings on MO: not in bad faith, but because I was viewing my asking questions on MO as only a temporary thing. Plus, I was ...

This MO question "Property $\Gamma$ in terms of correspondences" led us to answer two old open problems and to push further a third more recent result: Jon Bannon, Amine Marrakchi, Narutaka Ozawa. Full factors and co-amenable inclusions, arxiv/1903.05395. Thanks MO!!!

Ilya Bogdanov has answered my question Graphs with only disjoint perfect matchings on certain coloring in graphs, that emerged through research in quantum physics. This answer has inspired quite a bit of research: Quantum Experiments and Graphs (arXiv - cited Bogdanov's MO answer) Quantum experiments and graphs II (arXiv) Quantum experiments and graphs. ...

I think it is reasonable to be concerned, if only for the fact that we do not know what the ramifications of this behaviour are. However, I think it is better to describe the behaviour and call out what might be problematic about the behaviour. Right now, it seems we are getting OK to good quality material for the forum, and we have the ability to improve ...
