Like maps? Try The Map Room, a blog about maps. If you want to draw one from scratch, there are some software suggestions from readers.
Then there’s the second meeting of The Skeptics’ Circle. What’s that?

The Skeptics’ Circle is a biweekly carnival for bloggers who apply critical thought to questionable stories. Subjects include frequently repeated urban legends, quackery, pseudoscience, misinterpreted or denied history, analyses of misleading media, and any other articles or essays that fight misinformation with facts.

The minutes of the first meeting are here. Good educational fun.
Update: One more: I Ate my IPod Shuffle. Apparently, Apple originally compared its new itsy-bitsy product to a pack of chewing gum, and it inspired this guy to write a poem. It’s hilarious.
