  As you've probably read in these very posts, I am a comic fanboy...and I have kissed a girl. Several, in fact, but that's neither here nor there.
When I'm not working or doing social stuff, I peruse several comics-related blogs: here are my three faves, in no particular order: urlLink Comic Treadmill - reviews of comics both old and new, and currently focusing on the little reprint digests that DC used to put out.
Not about nostalgia; it's all about the comics. urlLink PostModern Barney - news, reviews, rantings, and snarky comments about comic covers of the past. And no, I'm not including it because he linked to me - honest! urlLink Progressive Ruin - The Greatest Comics Blog in the Multiverse. I am not kidding. Yes, they are all part of my blogroll, but go forth and enjoy. They're more fun - and informative - than you can conceive.
