How is Chatter different from social media tools?

Chatter uses a lot of the same paradigms that you see on sites like Facebook and Twitter, however, Chatter is completely secure and completely private. At the heart of Chatter is a feed with all of the things you choose to follow, like people, groups, accounts, and opportunities. You are in control. Chatter is not an app for monitoring other social media sites, like Twitter or LinkedIn.
