Facebook unveiled three new features today, and the most interesting among them is definitely groups. Yes, there was a “groups” function before, but according to Mark Zuckerberg, the only thing the two have in common is the name. The newly hatched tool allows users to create, uh, groups within their networks, and then chat or share with that group only. Behold, an explanatory video:

Zuckerberg and co also showed off a new download tool that allows you to download everything you’ve ever posted to Facebook, all in one file, and a new dashboard setting that lets users see how applications have accessed their data. “As you start having more social and personalized experiences across the web, it’s important that you can verify exactly how other sites are using your information to make your experience better,” Zuckerberg wrote on Facebook’s blog. “We’ve heard loud and clear that you want more control over what you share on Facebook — to manage exactly who sees it and to understand exactly where it goes.”

I think these new features look awesome, PopWatchers. What about you?
