Microsoft is testing a microblogging service called OfficeTalk that is much like Twitter. The service is designed for the enterprise and appears it will be offered as an on-premise service. OfficeTalk is being developed by OfficeLabs, the Microsoft lab for testing internally developed ideas. The service looks almost identical to Twitter. Microsoft says themselves that they are in the very early stages of development and because of this “the OfficeTalk microblogging experience itself looks very similar to other well-known services.” Microsoft is testing the service pretty much internally but is now accepting external requests from companies that want to join the pilot program. People create profiles. They communicate in 140 characters or less. You read the message of the people you follow. It includes a search functionality to find people on the service. A company feed shows the posts of all the people who are posting. Like Twitter, you can see the person's profile, the number of mentions, posts, followers and people who the user is following. It also has a url shortening service and threaded conversations they call comments.
