And also featured more in the past under its original name Sublevel:
Slashdot - Like HN, but far worse signal to noise
Reddit - If you are careful with the things you join, not actively bad
Twitter - I only follow a few people, and avoid politics
Facebook - Friend and family, where I vent
Flickr - Photo sharing
DeviantArt - Old photo sharing
LinkedIn - Facebook for your resume
YouTube - Lots of interesting things to watch, and comment on

For example, almost all Reddit's investing/finance subreddits are dreadful, but there is an exception:

There are really intelligent, fun communities on Reddit, but they can be hard to find.
Looks very low-key and less noise.
I would not recommend this lifestyle.
Twitter is not a community and I'm not on Reddit but not all subreddits could be called communities.
Aggregators are nice too, from all sides of the political spectrum to avoid echo chambers/censorship.
