It was a site started by some of the people from Television Without Pity (waaaay before Bravo bought the site). It had some random weirdly funny articles, and then forums for all aspects of pop culture.
Just lots of pop culture fans having (mostly) smart, snarky discussions about lots of things.
Some of the mods were not widely liked (and rightly so, in my opinion - some of them had some big egos, like them being "known" in some corners of the internet meant something more than it did). When they announced they were closing the site, they pretty much said "have at it" and stopped moderating.
Posters and former posters came out of the woodwork with guns a-blazin'. It was ugly, fascinating and hilarious.
