Office labs started a new project: OfficeTalk.
“Ever wish you could share information broadly within your organization without emailing everyone? Ever wish you could keep the pulse of what people in your organization think is interesting? Microblogging has that potential. OfficeTalk is a concept test to explore the value of microblogging in the enterprise.”
Which kind of means, twitter ( or yammer ) for the enterprise.
