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/

Slashdot
community/discussion is OK
You've got to be kidding me. It's "polite", I'll give you that, but these people are generally even more clueless that the worst of /prog/'s trolls. If a comment is right it's by chance, and moderation only reflects how well written it is (no surprises there - the same pool of retards is in charge of posting AND moderation)

I can predict 95% of the comments just by looking at the shitty sensationalist story titles. On some occasions, I've looked through dozens of 4+ rated comments, and not a single one came even close to being right. I've never posted anything there, in case you're getting the wrong idea.

The sad thing is that it's probably in the right place on that list. But if you disregard obvious troll posts on /prog/, I'm pretty sure it could switch places.
