Facebook is a contributing cause to the decline of society. It breeds narcissism and irreverence, among other horrible, horrible, horrible traits..
I deleted mine a few weeks ago and could not be happier.
To boot: every single click, every single view, every single page you view AFTER YOU LEAVE FACEBOOK, facebook tracks, stores, and sells to the highest bidder. Mark Zuckerberg is an asshole who stole facebook from ConnectU, and is now harvesting your information by means of daily changing privacy agreements, and other cunning things.
I have met Mark Zuckerberg and have some personal experience with him: he grew up in my town, his dad was my dentist. Hes an asshole, and he will fuck you over for a dollar. Don't trust him, dont trust FB, period.
To boot: dont let it make you into a narcissistic asshole who thinks that having 3,000 friends on facebook makes you hot shit, or further, that even 1 of those 3,000 people give a shit that you ate cereal for breakfast. Because thats what FB does: It breeds narcissism. It makes you think other people give a shit about the picture of a blade of grass you took, or about your thoughts on Obama/Romney/Paul. It makes you THINK people value your input, when your input is really nothing more than facebook garbage. If it held water past that, and your input IS important, you'd be giving the input in a relevant situation, to people asking for it. Not spewing it out on facebook. If anyone valued your movie review you'd be Roger Ebert, not John Smith on FB.
And then, you turn around and get pissed when someone whom you friended goes through all your shit.
The contradictory nature of facebook is insane. we have "privacy options", but no privacy! We put everything in the public sphere, but then get pissed when people go through our shit! We want to post about every drink we've had, ever drug we've done, but then get pissed when a future employer disqualifies us for it! We use it to "stay in touch" with people, but then neglect to stay in touch with them in REALITY because we're too busy checking out each others farms on FB!
Facebook is a giant contradiction.
