His website was a great help to me in college. I don't visit it much, but that's because his work has been incorporated into my intellectual foundation and I'm more interested in the upper levels now. His books are must-haves for any good intro to Catholic Christianity lists
I've visited his blog occasionally, but he seems to use it to make long acerbic replies to people who have just cut off arguments with him. Not having followed the whole discussion, I don't know whether they deserve it or not.
