Facebook has been fun for me, simply as a tool to re-connect with people I haven't seen or heard from in 20-40 years. I was the kid who left the neighborhood (cities, states, and countries) while everyone else stayed around. I never really went back to any of them. Now, seeing what old friends and relatives look like 40 years later, hearing about their lives, etc., etc., discovering/realizing that my old girlfriend isn't 23 any more, and now has 11 grandchildren... I find it delightful!!
I don't use Facebook to post what I'm doing every day. Not even every week. I don't play any of the games nor join any of the groups. While it's been wonderful reconnecting with all these people, we really have little in common, so aside from a "hey, I'm glad to hear everything has turned out well for you, nice looking kids, etc.," there isn't much more to be said. Facebook is a fun tool. We use tools. They shouldn't use us.
