Ask HN: Good Online Maths Communities?

85 points by achenet - 254 Days, 22 Hours ago Hacker News

Hello everyone,

I've gotten back into doing maths more seriously lately, and was wondering if there were any good online maths communities. Part of this is because there are some problems I'm stuck on, and part of it is because I think that much like hanging out on HN can help one become a better programmer, hanging out on a good math forum could help me become a better mathematician.

Does anyone know of any good communities? Math Overflow maybe?
