Do you really think that Facebook is the "best and worst" thing that has ever happened to society? I'm not hearing a lot of points for the "best" in your entry. And I'm betting that is because, like everyone else who is on Facebook, you feel required to say that. You make up this lie to tell yourself because you are fully addicted and you know that you can't stop. Therefore you rationalize away the giant black hole that sucks away at your life little by little. Think I'm exaggerating? Just try to stop. I wish you the best, but like all of the other Facebook clones, your life will likely feel too empty if you quit. There is no way out for you.
