Mootools Primer/Tutorial » Clientside CNET has this very cool Clientside website for its developers who manage the "client" aspects of CNET.com. They apparently have settled on Mootools as their Ajax library, and in fact have done a lot of extensions for it. Here, they provide a tutorial on Mootools and also information on all the CNET extensions! The rest of the blog looks very interesting as well. Of course, I love the fact that the lead developer appears to be a Mac user.
