Ask HN: Which online communities would you recommend for startup founders?

For online communities I recommend meatball wiki

quora is good, there are a few good subreddits, hacker news is great (obviously). my forum http://saasaholics.com might be worth a peek as well.

Surprisingly (or unsurprisingly?) enough Twitter proves to be very useful once you find the right people.

Also there's a cool facebook group if you're in Europe: https://www.facebook.com/groups/205823522802657/

Surprisingly, indeed. My experience with twitter is that it's not a very good communication medium, let alone a community-building one. You can follow "the right people" all you want, but without being followed, the conversation is rather one-sided.
