Sun is doing something big with java.net. If Sun is a hornet's nest, they have peeled back much of the skin around the nest with java.net, exposing a wild variety of interesting activities that invite the Java developer community at large to join them through a mixture of weblogs, wiki, directories, repositories, and pseudo-magazines.
End result is, well, confusing. But, it is an enjoyable kind of confusion, not unlike being dropped into a new city being built. If it was a city, I would say the city center is the Java Today page. Drop in and check it out. Unless I misread between the lines, I think there is a new bold attitude at work here.
