Snopes.com has a message board where people talk about that kind of stuff, too, I believe. I haven't been an active member of Snopes in a couple years though, so I don't know how dead their board is. But I remember it was a pretty fun place for just watching people talking about weird stuff in general. Lol.
And if you get into the conspiracy videos on YouTube and start clicking the related links you will really get into the Twilight Zone. Just be careful about leaving comments and stuff; some of those people are nuts!
