We have Yammer, and while we're cleared to use it to discuss company confidential information, most people use it as a virtual water cooler rather than for any work stuff. Most people create a profile and either lurk or don't bother with it.

Seems we are working for the same company ... ;) plus we use chatter on SF.com for some user on iPad
