Facebook has begun rolling out a new feature that's bound to charm the political activists among its users. Called "Community Actions," it lets Facebook members create an action page where they can describe what they'd like done, and set up a button that like-minded members can click to show their support. The page will show the government agencies and officials notified about the action, as well as the number of its supporters. When you support an action, you'll be able to see any of your friends who also support it.
