"Facebook in a Crowd" by Hal Niedzviecki

An individual on facebook had about 700 friends, but was realizing he wasn't spending enough time with his real friends off of facebook. He wanted to throw a party, so he invited all of his friends online, and a lot of people said that they would be attending. But, when the party finally arrived one person showed up. This comes to show us, that the definition of a friend is different online.
