Hey, thanks for the plug. My writing about Iron Man so much lately (in conjunction w/the movie) has really increased our traffic. I had no idea it would; after all, my writing about comics in the past didn't do much for hits. Obviously, the movie has generated a LOT of interest in all things Iron Man, though.
That said, I HIGHLY recommend Mark Engblom's site noted above. He has an incredible knowledge of comics, writes extremely well, and has a terrific sense of humor. His original graphics are first-rate and downright hilarious when they have to be!
