From the About page drop-down AJAX thingee:
dzone.com (DZ) is a link-sharing community where member participation determines what gets published and what does not. Members submit links to developer-related content into a queue, and you vote to indicate whether or not you like those links. Popular links are automatically promoted from the queue to the front page and thus get more attention. This "social filtering" process provides everyone in the DZ community with access to focused, categorized content that has already proven to be of interest to other developers. The process works well, but it works even better if you participate. Start by clicking the "plus sign" next to the vote count of any story you enjoy, and your vote will immediately be factored into the rankings. You can also explore the queue of newly submitted content to see what's coming up and help select what gets promoted. Of course, if you have content you'd like to share at DZ you can submit new stories any time.
