Looks like Java's jumping aboard the community Web bandwagon and launching java.net. It's wiki-fied (though currently still sparse), blogified, and mini-portalized. It seems to have much more potential than the old Java Developer's Connection, which had to use karma contrivances to get people to participate. At this stage, though, it's hard to tell if people will jump aboard. Nevertheless, it's nice to see that they're using Wiki (but Sparrow is better).
