The internet has been a boon to atheists, as many of us feel like islands in a vast ocean of theism, with no other castaways in view as far as the eye can see. But, via the web, we can hold conversations with an atheist halfway around the world as easily as with one 2 streets over. This is the ideal environment for blogging, and a number of excellent atheist blogs have sprung up to serve the diverse, diffuse, and often lonely atheists of America, wherever they are.
One of the best is Hemant Mehta's The Friendly Atheist. Hemant is best known for "I Sold My Soul on eBay", a publicity ploy in which he did just what he said and got a winning bid from a devout Christian who wanted a crack at him for a day. But he didn't stop there, and his blog is well worth checking out on a regular basis.
Most recently, for example, he featured a little autobiographical sketch from Rachael Slick.
