I found facebook became more valuable to me once I decided I would only post about things I want my friends to know. That is pictures of my kid's new bike, or a video of the baby babbling. Facebook does a very good job of ensuring my close friends and family keep up with the cute little things in life.

I'm still working on getting out of all the groups that waste space. Sadly many useful things have moved to facebook, and while good for facebook (more ads), other forums function better for keeping up with my hobbies - except for the lack of people checking them.
