Social networking with Chatter

Chatter is a combination of Twitter and Facebook like collaboration tool for business created by Salesforce. People who wish to join your Chatter must use your business email. So its a way of using the best of Twitter and Facebook but in a more closed environment where you can collaborate with other team members of your company or business. I have added a video overview of Chatter created by Salesforce. At the moment the service is free.
