Here's a lengthy examination of Bizarro, a character that works best in short bursts.
Also, I had no idea that the comics letterer Todd Klein has a blog. He writes about what he's reading, mostly Vertigo and DC stuff but books and art, too. And he sells some prints of his own work. I'm thinking of getting either the King Arthur or the Pegasus/Bellerophon.
On a related note, here's a bunch of jokes, courtesy of Vulture.
Here's an examination of what recent Superman stories have done with the idea of Superman, courtesy of The Atlantic. This one's gotten a lot of attention lately.
And it's always nice to see an appreciation of Moore and Gibbons' "For the Man Who Has Everything."
