Last night was the official Facebook Prom for all the employees. Valleywag has the scoop with some not so clear photographs of the beginning of the event. Facebook rented out the 4th floor of the Metreon. So why did they hold a prom and not a formal? Apparently the company would like employees to feel like they are still in high school to keep them youthful and creative. Whatever the rationale behind the event, it went off apparently without a hitch.

Julia Allison was also invited but ended up deciding not to roll to the event. Perhaps it brought back memories of those awkward years that many people don’t want to remember. One of the potential reasons of hosting the event was the sponsorship by Sony Pictures who is promoting their upcoming movie “Prom Night” on Facebook. One of the other partnerships was with Sears.

No, Facebook employees are not scrambling to find mobile houses, they are instead looking to have free prom dresses thanks to the new prom dress sharing application that Sears created. 2008 is the year of high school graduation for Facebook and now they’re all going to college so it’s time for the team to grow up. That means management changes, employees leaving the company and internal tension. At least the company can have one last fun night before Facebook Connect jumps into full swing.
