So you say you're going to give up Facebook (for a bit) in 2012? Mmmm - no you're not.
But if you're reeeaaally committed to that resolution (blasphemy!), there's a site out there that's committed to helping you and others get offline, off of Facebook and checking into real life instead (uh huh) - visit Facebooksabbatical.com.
So update your status (per their instructions) with a picture, announce it to the world, deactivate your account and let the shakes begin.
