...really great comics. in particular i'm pretty excited about this one about social awkwardness in exiting conversations: hyperboleandahalf.blogspot.com/2010/09/four-levels-of-soc...
Beautifully written & hilarious; I read the whole blog like a book & laughed until I cried at every entry. She also includes hilarious illustrations.
Cons: The only con I can think of is that while she updates regularly, it's not nearly often enough for my taste.
