I rarely get on Facebook. I primarily only use it for family get together and class reunion info. Occasionally if I am bored I will take a look at it and realize why I don't spend much time on it. I especially despise the posts of people who put nothing but stuff about racism in everything they put on Facebook. I end up unfriending them. The stupid chain mail and MLM posts are very annoying.
Also updating everything you or your family is doing every couple of hours is unnecessary. If it is important like a death in the family or you going into the hospital, fine. Talking about what you just ate, leaving cryptic messages about your bad day, and taking selfies all the time is stupid and will likely cause people to miss out on when you actually have something important to say because they start ignoring you.
