Just wanted to take the time to plug the JavaCoder.Net web site - a handy site put together by one of my pals that is helping me stay in touch with the world of Java. If you get the time, please take a look. It's very fast and completely free of adverts.
The bit of the site I really like is the rapid way of accessing information about java design patterns (much quicker than Sun's site). The java discussion forum is also worth a look and I would encorage you to contribute to make the site richer.
