I have ZERO information on my profile, not even a picture of me. I ONLY interact with people that I know in person, mostly a handful of relatives and a few close friends that live far away. I don’t FB with friends that live nearby. I either see them in person, e-mail them or call them on the phone.
I don’t play games or fiddle with any apps and I use the custom button everytime I post anything, to make sure that what I am sending out only goes to those people who I want to see it, instead of sending it out to everybody.
I only post photos (and I’m sure to make sure that the folks in the photos are OK with being posted before I post them, especially when children are in the photos. Some people do not want photos of their kids being posted online for a variety of reasons). Sometimes I’ll post a silly little piece of info about something that happened to me and I also post little mini reviews of restaurants around town that I’ve been to or pictures of food that I have cooked.
I stay away from posting anything about politics or religion. I already know where I stand and it’s not my place to try to influence anyone else what to think or believe. If I see controversial stuff that’s been posted by other people, instead of arguing with them, I just ignore it, or even block it.
I usually check it once a day, to make sure I keep up with my family’s comings and goings and to check messages (usually about family events that I’m attending or news about my family).
Don’t get caught up in people’s requests to play games or deal with apps, just decline. If anyone asks you about it, just tell them that you use FB in a very limited manner. If you get any “friend” requests from people that are not close to you, simply decline. Again, if any of these people ask you why, tell them that you are really limited with your FB use.
Never post anything that you’d be embarrassed for your parents or your children to read/see.
I make good use of the privacy settings too. Facebook can be useful and it’s not necessary to get all caught up in the drama, if you use it wisely. Good luck : )
