Serena Software, a company I previously mentioned because they allow employees one hour per week to work on their Facebook profiles, has apparently taken Facebook further than anyone ever thought would happen.

First reported by SDA Asia, and then FASTForward Blog, Serena Software has taken to using Facebook as the frontend for their corporate intranet. Different folks in the company post links to information which is stored behind the corporate firewall.

This is an interesting spin on adding a social element to the typical intranet. I’ve worked with companies that host blogs within the intranet as well as discussion forums. They have also created sections of the intranet where an employee can build their own profile complete with photos and outside of work interests. Doing the same thing, but with Facebook, Serena Software saves the cost of development and hosting the application. They also gain interconnectivity with partners and potential employees.
