sigh No. This rumour comes up every year. It's become an online tradition. People believe it more this year because of the news of SOPA and PIPA and Wikipedia shutting [ITSELF] down for 24 hours yesterday. But no, facebook is not shutting down.Only believe official statements from facebook, either on Mark Zuckerberg's page (https://www.facebook.com/zuck), or from facebook's official blog (https://blog.facebook.com/). If neither of those says anything about it, then don't believe it.
