I refer to this question by André Henriques. It is nonstandard, and prima facie there is a clear case for closing it, and at the time of writing there is one vote to do that. However, I personally feel that this is an interesting and valuable question where the MathOverflow community can provide insight that would not be readily available elsewhere. So I thought I would open this space for discussion.
In my view, the value of this question lies in the fact that, whereas each one of us is aware of the changes which our own institution has made, it is very likely that each person/institution did things slightly differently. So there's a lot to be gained by exchanging information.
For example, how does one deal with undergrad exams under pandemic circumstances?...
I'm sure that there's more than one way of running undergrad exams, but I'm only aware of what my own institution has done.
Here's another example: because of the pandemic, I decided to build a lightboard at home in order to give my classes (this was inspired by Ivo Vekemans - here's an example of him lecturing). Some people might not have been aware of lightboards...
However, I personally feel that this is an interesting and valuable question where the MathOverflow community can provide insight that would not be readily available elsewhere.
That argument could apply to lots of off-topic questions, so I don't find it convincing. I suggest that we stop considering "but I want to reach mathematicians, and this is the largest community of them" as a valid argument at all. This criterion is too prone to abuse, and could apply to just about anything, for instance to an advertisement for office chairs.
You should not argue why it's good for this question to be seen by mathematicians; it's about why it's good for mathematicians to read it. And why it is on-topic on a Q&A site about mathematical questions, rather than on a blog, a news site, or another SE. If you cannot find more compelling reasons why MO is the right site for this question, in my view this is a red flag.
I think these close/open fights are very unproductive. Personally I feel like this wasn't a great fit for MO and wouldn't have asked it myself, but I respect André's opinion a lot and if he thinks it's a good question then maybe I'm wrong, and I don't see what the point is having a big fight over it which is never going to resolve (in particular, because SE has such useless tools for this situation).
In my perfect world we'd have some system to allow some of these open-ended questions but at a rate that doesn't cause a problem. A reasonable open-ended question every few weeks is totally fine, and it seems like there should be some way to get to that without having an ugly fight every time.
