I heard about Everybody Hurts: An Essential Guide to Emo Culture in Believer Magazine a while back. It's funny at times, with some good illustrations. I enjoyed being able to point to parts of the emo taxonomy and say "I know someone like that... and that guy... and that one..." And for the emo consumer, there's a pretty good round-up of what you should be listening to, where you should buy your clothes, etc. The writing is really chatty, though, and I couldn't help but feel that they were stretching to make a target word count.
