Just read this Slate article about a woman who didn’t know that someone had found her laptop in a cab and was trying to contact/help her by writing to her on Facebook, because Facebook effectively hid the message in this ‘Other’ folder that only appears when you click on ‘Messages.’
So I just clicked on MY ‘Other’ messages and found this from November 17th! Damn you Mark Zuckerburg now I missed my chance at love and happiness and raising a Doughter named Miracle, and, more importantly, a decent chance to go to the 2012 Olympics b/c this guy is a God fearing DOCTOR who lives in Liverpool! That’s in England, Mark Zuckerburg!
May God Almighty Blessed and Guide you, Facebook. NOT.

BUT, you should actually check out this Other folder, because, although much of it will be Spam, you may also have missed some good or important messages!
