Every once in awhile I will "take a break" from my FB page. I would LOVE to disconnect from FB; however, the friends on my page are people that I grew up with (K-12, same track) and a few family members that I don't see very often.
I seldom post anything of significance & NEVER post photos of myself (that's another story in another thread).
It's the only way I can keep in touch with people in my life other than snail mail (which I love and continue to send little notes even in this day and age).
I don't have internet / cable at home, so it's actually a motivator for me to drive the 35 miles or so to come in to the office

Especially after a long weekend alone. Almost everyone I know is married, has children, a family, does "stuff"...I love reading all the nice things.
Crazy as it sounds, too, two friends are battling cancer (bless them), and they or their SO's keep everyone up to date on how they are doing. And they get lots of support and lovies from far away and distant lands.
