Find Your Facebook Valentine—the Person Who ‘Likes’ You Most Often

Thank them with Y&R and VML's app

Y&R New York and VML have whipped up a simple little Valentine's Day app called Who, Like, Likes You? that lets you discover your Facebook Valentine—i.e., the Facebook friend who has "liked" more posts of yours than anyone else recently. As the app warns, nine times out of 10 your Facebook Valentine isn't your significant other, so be judicious with your notes of thanks.
