Sitepoint really was the beginning point for me to learn all of this stuff and find other website's like Chris's websitepublisher.net. Unfortunately, its not worth visiting very much anymore.
They wanted me to write one of their "kits" for them. I was thinking about going with it, just so I could have my name plastered all over the site. However, I talked to Dan Theis who wrote their Search Engine Marketing Kit, and he had a very bad experience with them. First, he thought he was writing a book, then they changed their payment terms from quarterly to yearly! After I heard that, I said no thanks.
I think Sitepoint has its uses, but like WebmasterWorld really has some bad points.
