One of the things that always bothered me was that I never knew where to send discussion questions. I just knew that MO wasn't the right place for them. Homework questions could be directed to various sites; meta questions come here; encyclopedic questions go to Wikipedia or n-Lab (or a book or the arXiv). But discussion questions have no home unless you happen to run a popular math blog, which is too bad since discussions can be fun.

The other day it occurred to me that perhaps we should direct discussion questions to math reddit. I always thought it was just links to outside sites, but it seems like discussions are quite common there. Unless somebody with more reddit experience says we shouldn't send discussions there, I'm going to start doing it.
