Top Atheist Blogs
If you're looking to increase the number of your atheist blog subscriptions, a good place to start is this list from Challenge Religion. It's a daily list of top atheist blogs. Two of the blogs I subscribe to are in the top 25. Many of the rest I've never heard of. One is conspicuously absent, though a couple of posts from there were listed in the "Upcoming Stories" list at the bottom of the page.
