> The hacker sees facebook as personal, and email/phone public. The average person sees facebook as a public place, and email/phone as a personal channel.

Upvoted just for this. Not sure if it's true or not, but it's a provocative thought.

Sorry, I don't understand how email could be seen as public, let alone the phone. (Except in as much as they're not secure channels, but neither is facebook.)

Could someone explain what this means?

I think the poster means that for the average person Facebook is the channel you maintain for people you know publicly (i.e., weak social interactions) to contact you, and email/phone is for your inner circle.

For some of us it's the other way around: email and phone is how people we don't know well contact us, reserving Facebook and Twitter for closer interactions.
