Yeah, I'm on it. Basically it's Google's version of Facebook, only with better sorting features. You can organize your followers into "circles" like "friends," "family," "acquaintances," etc. When you post something (a link, photo, status update, etc.), Google+ asks what circle you want to send it to. (Kind of like a modern version of the old "Clippy" animation from Microsoft Word. "Are you sure you want to share that drunken party photo with everyone? Why not just send it to your 'friends' circle? I see you're composing a letter...") Circles makes it easier to share things with your friends that you wouldn't want, say, your mom to see. Which you can basically do on Facebook already with the "groups" feature, but Google+ is all about the selective sharing thing. (I do like the idea of creating incredibly specific groups. Like "friends who enjoy Game of Thrones-themed viral videos" or "people who love the late-'80s Bill Murray movie Quick Change.") There's also a "hangout" feature which lets your friends know that you're available to video chat or IM or, uh, hangout I guess. It's sort of like Skype with a bit of ChatRoulette's randomness. There's also something called "Sparks" that recommends links for you based on your interests which I haven't bothered with yet, Right now Google+ is invite only, though it doesn't seem all that exclusive since I've received like ten invites in the past week.

One advantage it has over Facebook is that you can check your notifications and activity on GMail or any other Google application, which is good for people who are on Gchat 24/7. You basically can do all your social networking without ever leaving your email. After they work out some of the bugs, it could be a good place to share stuff online with your social circle.

That said, I don't see how it's all that different from Facebook. Also, until Google+ integrates into Facebook and TweetDeck, so that you can update all three simultaneously, it's just yet another online garden to prune. I can definitely see people getting into it (the idea of sharing with specific groups is appealing), but I don't see everyone jumping ship from Facebook any time soon. Facebook has just been around too long. We've all built our virtual houses over there with friends, coworkers, family members, old classmates, and exes and the idea of starting over with another social networking site that doesn't offer anything all that new just makes me feel tired. More photos to upload. More people to add or re-add. More relationship statuses to set. (Also apparently "divorced" is not considered a relationship status by Google. Who knew?)

Also, I wonder if the "circles" thing will create drama. Like, will someone get offended if you put them in "acquaintances" while they have you in "friends"? From what I've read, it seems like your followers can't see what circle you put them in. But, it's bound to create some drama. Like, what if your friend Tim gets included on the hilarious video you share with your "friends" circle. Then he asks your mutual friend Steve if he saw the video you posted. Except Steve is in your "acquaintances" circle and wasn't included on the video. Now his feelings are hurt. As much as we want to keep our online lives private and selective, the system tends to break down once our real world lives start to creep in. But, if you're looking for a place to share stuff that you don't want your parents and boss to see, Google+ will probably be for you.

But the new social media site I'm really obsessed with is TurnTable.fm. It's basically Pandora, but you're the DJ. You pick an avatar and join themed music rooms (indie, '80s, pop, etc.) or create your own. There are five DJ slots in each room. You can either listen to the music and vote songs "lame or "awesome" or join in and spin. Make a setlist from the site's vast collection of songs or upload your own MP3s. If someone votes your song "awesome," you get a DJ point. But be careful to keep the theme of the room going, lest your tune be voted "lame" and skipped. You can also buy songs you like through iTunes and other sources. As a way of sharing music with friends and like-minded strangers, it's unbelievably fun and addictive. I could definitely see the site taking off on the social networking/dating side as well. Since every room has a chat area, it's easy to strike up a conversation about music with another user and see what develops. It's also still in the early stages right now, but if you have a friend on Facebook who is using it, you can get in.

Are you guys on Google+ and Turntable.fm? Would you join? Or are you sick of all the social networking sites? Do you long for the days of Friendster? Were we ever so young?
