I recommend a visit to NoBeliefs.com. Among the highlights you find collections of great articles such as:
Did a historical Jesus exist? - a topic that I sometimes talk about here at Something Surprising. The more I read, the more I am skeptical about it.
Problems with Islam - another topic close to my heart. This is a great collection of articles on the topic from people who came from Islamic backgrounds and others.
Problems with Creationism - more evidence that there are few aspects of Creationism that do not have problems.
There is a lot more there too. Go and have a look.
