Yea but that's also a reason to leave. I know one of the main reasons I stopped using Facebook for photos was because I didn't want my Mom and extended family looking at the parties I went to at college.
That is why I have to remain. I want my mom to see pictures of my kids. I want to see pictures of my nephew's lip after he got hit with a ball (6 stitches). The girl who took 4th place in the state dance competition is of interest to me because I remember her mom from high school - the first place dancer is nothing to me. The real things in life that matter are why I'm on facebook and why I cann't leave.
Politics and some hobby groups are on Facebook and interesting, but the real meat is the personal photos and stories that would never be in the news.
