Weekly Poll: Where Do Developers Hang Out Online?

In this day and age, we can't deny that we rely on social networking to let us know what's going on in the world. Given the variety of options available to the social networker, it isn't uncommon to belong to many different communities, and even to specialize on each community- Facebook for my personal things, Google+ for my hobbies, LinkedIn for my professional media- the list goes on.

DZone, being a bit of a social network ourselves (though much more too), is wondering where developers do social networking. Which sites do you use frequently or not at all? Which do you use for development-specific content? And, as a special treat, those of you interested in Google+ will have a few bonus questions at the end of the poll. For those interested, you can review the results instantly after you complete the poll.
