At first (for the first year) I was the same way. I didn't want something else to "check" that would waste my time. I didn't care what was going on "up to the minute" with everyone.
But, slowly, I started to use Facebook more and more. I get a lot of "friend" requests, but I only accept those from people I really want to hear from. Some of my friends are past employees, family, my veterinarian in Alabama, past clients of mine and other people who I find interesting, talented, smart and funny. When they post something it is of interest to me. It keeps me in touch with their lives, and they in mine. It is so easy to share photos with everyone with just one click -- emailing is so difficult in comparison.
My little group doesn't post boring, trivial stuff but instead posts things that we really want to hear about.
I recently posted photos of The Villages, and now one of my past clients is coming to check things out -- I'll bet they buy a home here!!
Anyway, now I love facebook. To each his own
