(Telecompaper) Facebook is developing an office version of its social networking website. The new service would compete with sites such as LinkedIn. Dubbed 'Facebook at Work', the service is expected to allow office employees to chat with colleagues, connect with professional contacts and collaborate over documents, the Financial Times reports, citing unnamed people familiar with the matter. The new site will look very much like Facebook with a newsfeed and groups but will allow users to keep their personal profile separate from their work identity. Facebook declined to comment.
