Link: The Panda's Thumb.
The Panda's Thumb is a great website. It discusses all aspects of evolution and biology. There are articles dissecting Intelligent Design/creationism, reporting current events in science and also very detailed, technical, but (mostly) readable, articles on the latest advances in evolutionary biology. It provides a real service to the public.
A typical series of articles debated whether it was wide to debate creationists and compared the argumentative style of creationists to those of other fringe movements. Read and enjoy.
