I just noticed that the on-topic of this site does "not work" (it is currently the site's name, Mathematics Educators, but this is does not really fit for our name).
The problem can, for example, be seen in the tour [my emphasis]
Mathematics Educators Stack Exchange is a question and answer site for those involved in the field of teaching mathematics. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about mathematics educators.

How to Ask
Is your question about mathematics educators? We prefer questions that can be answered, not just discussed.
The question to be decided is: What should the on-topic say?
Whatever you suggest please make sure it works in the phrases I mentioned above in place of "mathematics educators" (it is my understanding that each site has "title", "on-topic", "target audience" and these get used at various places on and off the site, so there is not much flexibility).
In some sense, we had a lot of dicussion and even a vote on this already as most proposals for the name we had would have worked; see https://area51.meta.stackexchange.com/questions/13356/vote-here-to-decide-the-name But we could also have another discussion and/or vote.
