> Some people can't be accessed without Facebook.

That means that the people who cant be accessed without facebook had to voluntarily cut themselves off from email-only people first. And while doing that, they had no concerns that they will be missing connectivity, because from their POV the email-only people obviously had such a low social rank anyway, that they simply could afford to sorta blackmail them ("either you get a facebook account or I'll simply cut you off.") without any fear they could be losing anything of (social) worth.

Getting a facebook (or MySpace/ICQ/MSN/AIM/YIM/whatever 1-vendor-only proprietary network) account just because someone forces you to do it is a way to confess to yourself that you must have be pretty low in the pecking order in your desired social circle and that involuntarily creating accounts with service-de-jour wont be the last thing you'll be forced to do to avoid being cut off. Or, alternatively, just get real friends.
