I have been a user for 6 months to a year and when I started my business I started a facebook group page for it and invited all my friends. I've gotten a few gigs off of it- high school seniors and some friends of mine from high school. The thing is, it is an amazing networking tool. You tag your client in it if they are you facebook friend and then all their friends see their pics as well and are directed to your facebook page. And the fact of the matter is I know grandparents and uncles and aunts that are facebook users. And I live in KS, not exactly a technocentric part of the world. I vote yes on facebook, here is a
link to my facebook group if you want to see it.
