Facebook is launching Facebook at Work (FB@Work), a new communication app that aims to expand the US firm's presence within offices and other places of work. The software is designed to provide a way for users to communicate as an alternative to email and other intranet systems.

Facebook says information posted within the service is kept "secure, confidential and completely separate" from personal Facebook profiles.

"Facebook at Work is a separate experience that gives employees the ability to connect and collaborate efficiently using Facebook tools - many that they're likely already using such as News Feed, Groups, messages and events," the social network said in a statement.

"The information shared among employees is only accessible to people in the company."

Facebook at Work is in early pilots, but when it debut, it could threaten other established collaboration tools targeted at businesses including Microsoft's Yammer, Jive and MangoApps.

In related news, Facebook has announced today that it?s making its Internet.org app available in Colombia.

The news marks the first time the app is available in Latin America, and it will provide access to some of Colombia?s government services for free.

A number of services will be available for free use in the app in Colombia; 1doc3, 24Symbols, AccuWeather, Agronet, BabyCenter, Girl Effect, Messenger, Mitula, Para la Vida, Su Dinero, Tambero, UNICEF, Wikipedia and YoAprendo.
