Xkcd is great, I have read his books and most of his comics. It helps when you are a science or tech geek, but there are some good ones in many subjects. He wrote an entire science book using only the 1000 most common English words. It is a very interesting read.
Oh, and mods should look up his comic on freedom of speech on a forum. A little language prevents me from posting it, but it is a good laugh for anyone who has done moderation on a forum.
