These are three sites where I get all my comedy news.

Aspecialthing. Matt runs a great site. It both reports the news and has the absolute best comedy message board. If you like to discuss comedy with nerds then you should be on this board. Best place to be informed about LA comedy.

The Apiary mostly covers NYC comedy. It also has lots of links to comedy videos and blogs. Times may have changed but when I was in NYC the only press that covered comedy was Time Out. This guy is filling the void.

The Dead Frog. Todd is a great reporter. He goes to festivals. Really does his research. He covers trends in mainstream comedy as well as what's going on in the alternative world.
