But the most important rule (or at least the only one that everyone agrees on) is about Facebook stalking: It's not cool to dig through someone's old pictures and like stuff from several years ago, and it's way worse to bring up all the stuff you learned about your friends from their profile in real life. Only a total creep would do that.
Here's an uncomfortable fact: Every picture you have on your Facebook profile has been stalked, multiple times, by everyone. All your friends, exes, former professors, employers, acquaintances, friends-of-friends, and prospective OKCupid dates have seen every picture of you there is. In fact, Facebook stalking is what Facebook is for -- so much so that some think the website is actually training us to be voyeurs.
Remember, the whole point of Facebook is connectivity, so complaining about privacy on it is just, like, the weirdest goddamn thing. At the end of the day, Facebook is basically just a weird blog platform, right? And yet it has somehow convinced us to think of it as a private place to put our personal information -- even though it's on the Internet. Seriously, how insane is it that we all fell for that? Thank God Mark Zuckerberg didn't go into drug dealing.
"Don't worry, this shit's totally safe. It's like the Facebook of heroin."
