MetaChat is an informal place for MeFites to touch base and post, discuss and
chatter about topics that may not belong on MetaFilter. Questions? Check the FAQ. Please note: This is important.
I don't know about MonkeyFilter, but I'm guessing it's similar to MetaChat in that threads are made up of real people. MetaFilter, on the other hand, is made up of Internet Constructs engaging in pissing contests and oneupmanship. Which is fine, if that's what yer into, but going drinking with MetaChat (and, I'd imagine, MonkeyFilter) is a lot more fun.
Speaking of which, we should get drunk, MetaChat. Soon. I won't grab your ass this time, promise.
