I used to love Quora, but lately I've found it really hard to enjoy. There's a lot of crappy content. I heard they're trying to change this somehow, I'll wait to see. There are some subreddits that are pretty great: /r/askhistorians, /r/credibledefence and /r/neutralpolitics are all pretty good. LessWrong.com has some good reads, and so does ribbonfarm.com.
