@HarryGindi yes there is. although like everything else on twitter it can get mixed into a lot of different things. I'm on twitter, along with Emily Riehl, Eugenia Cheng, John Baez, several of John Baez's students, a lot of undergrad math majors, and some other people who read but don't post much (e.g. Charles Rezk).
And yes, I agree that we should probably avoid "political" stuff in here. I have extremely strong opinions about a lot of stuff, and aside from doing my best to keep this room from getting abusive or toxic, I try to leave my opinions out of it. However, if you'd like to get involved in a nice yelling match about your topic of choice, twitter is really a great opportunity for that.
