Best/Worst prog. communites

How would you rank the various programming communities? (Bonus points if you explain whats good/bad about them)

Here's my list:

1. Hacker news (links can be meh, but it has the most interesting discussions)
2. Stack overflow (community is pretty dry, but for general programming-related issues that google isn't helping with you can get high quality answers)
3.  Slashdot (lots of stories about shit nobody cares about, but community/discussion is OK)
4. /prog/ (the endless trolling, punctuated by anti-troll troll posts can be entertaining sometimes)
5.  /r/programming (links are pretty awful, discussion quality worse than /prog/, most commenters appear to know nothing about programming)
6.  /g/

/prog/ is basically shit. It's only good for non-programmers to brag about which CS 101 books they've read and argue about which is "teh best progamming languege!" At least people on Hacker News and /r/programming can program and actually have careers in the industry.

I only come here to troll anonymously.
