Status

Updating your Facebook status is the quintessential path to instant gratification. Feeling lonely? Send a quote, an inside joke, an offhand observation, or a gripe out into the void, and nine times out of ten, you'll get a couple "likes" and a sympathetic comment or two within an hour. It doesn't matter that they're usually from people who'd forgotten you exist until it popped up in their minifeed. It's human contact, it's validation, and sometimes, that's all you wanted.
