General: 20 Sites for Java Developer

One of the advantages of all of us having different backgrounds and perspectives is that we see different things from day to day and can share unique information. This is especially true when it comes to the internet. I thought I would try to start the ball rolling on a discussion of hot Java sites. We all use and love Javalobby, but there is so much content out there besides what you can find here. So I will start by listing twenty sites that I think deserve the merit of being checked regularly. I hope you'll join the discussion and post any sites you check that are Java related and worth mentioning!
