Carl Zimmer, the extremely well regarded (by me) science writer, and Phil Plait, the author of the popular astronomy blog Bad Astronomy have a conversation up at bloggingheads.tv.
This video is pretty long at 57 minutes, which is why I posted it on the weekend. My favourite part? The Buzz Aldrin punching a moon-landing conspiracy theorist! Classic!
Carl Zimmer also has a website (including a blog).
