Added (quid): I am reactivating this in the hope of getting a clearer view of the communities opinion. I suggest we discuss this in general, keeping the self-learner aspect in mind but not as unique direction for the discussion, followin OP's wish.
Apart from our site name, the first thing a new visitor is most likely going to read is the “subtitle”:
Mathematics Educators Stack Exchange is a question and answer site for those involved in the field of teaching mathematics. It's 100% free, no registration required.
As already noted during the poll on the site name, one of the drawbacks of the site name Mathematics Educators is that, while having the advantage that it does not attract questions about math itself, it is everything but inviting for self-learners who want to ask on-topic questions. As a result it was suggested that at least the subtitle be welcoming for self-learners, should we decide that we welcome them. As this seems to be the case, I think that it is time to rediscuss the subtitle. (Note that this issue was already discussed on Area 51, however, on basis of another site name.)
I am therefore asking for suggestions and other considerations for our subtitle, including other issues than self-learners. I think it is best to hold a seperate vote, should the need for it emerge (i.e., if there is no clear consensus here).
Keep in mind that we need to be careful to avoid attracting questions about math itself and hence titles like the following are arguably not a good idea:
Mathematics Educators Stack Exchange is a question and answer site for math educators, enthusiasts, students, professors.
