I find Slashdot very useful in general.
If anything is twisted or taken out of context in the blurb, it's almost always picked up very quickly in the comments.
Also, they have a user-controlled feedback system. If you want to avoid idiots, you can just read the posts that have been moderated high. If you want serious replies, you can just read the posts that have been moderated as "insightful". All that can be done automatically.
I suspect that you don't like it there because the people are a pretty even mixture of pro-Linux and pro-Windows. It's rare to find a place that's balanced so nicely, but it's also rare to find a place where the majority of people don't agree with you that Windows is better. Doesn't it bother you when people poke fun at Windows just because IE can't open a .pdf in a new window properly? (a problem that's been driving me nuts.. I might post about it in web dev one day)
