Tobias has a great post linking to several atheism sub-topics and the 17th Annual Carnival of the Godless: LINK.
And here’s the webpage of interesting weekly podcast on skepticism and debunking. The podcast are a little slow moving, and the hosts lack polished interview skills. Don’t let that disuade you though, they’ve gotten some great guests (James Randi,
Michael Shermer Benjamin Radford) and the don’t shy away from touchy subject, c.f. their 2nd show, which was about Ghandi. For fans of Penn & Teller’s Showtime debunker series Bullshit!
