I have a grand total of 8 people I know in real life that I consider friends. I don't need facebook to keep up with that few people.
FB isn't just to keep up with people you know. Meeting new people and following sites of "famous" people is not a terrible thing.
You're a good conversationalist; I think you'd have some fun on it sans Farmville and Mafia Wars
But if he decides to quit, he'll get sucked into
the TRON world
the Facebook Matrix and forced to play Yahtzee for the amusement of... something, like this young man did.
I had FB for a very, very short time because I just didn't see any reason to keep it. I met a few nice people, but everyone else was either... what's a good way to put it? Phony friend-addicts? Something like that.. or they were just hitting on me, some in quite disturbing ways (seriously, some sounded like potential stalkers).
And I refuse to play Farmville because I'm already on morphine, so I'm afraid to mix two addictive substances. I might OD.
