Facebook has officially entered the productivity space with the launch of Facebook At Work, a version of its social network designed specifically for the office. The enterprise version was announced Wednesday, according to various reports.

While Facebook At Work looks and feels like the social network we've all grown accustomed to, it is meant to be used as a collaborative tool among colleagues that could replace the use of email. It also feature a few key differences from Facebook. Most notably, Facebook At Work does not feature advertisements or track user activity.

Facebook has not said how it will monetize this new venture. One option would be to charge businesses a subscription fee. Facebook At Work will hit the Apple App Store and Google Play on Wednesday, but unfortunately for eager users it will only be made available to a few test businesses as Facebook plans a soft launch.

With Facebook At Work, the Menlo Park, California, company is taking on the established productivity players of the world, some of whom already offer social networks designed for businesses. Microsoft, for example, runs Yammer while IBM offers Connections.
