Trying out Yammer.com

Want a Twitter like app just for your company?  Try Yammer.  Its almost exactly like Twitter only you can create a community for people only in your domain (email@domain.com).  It could also be described as a group IM that is always setup.  Let me know what you think!  I'm still undecided.  It's definitely cool, but I can't tell if it really helps productivity.
