Yesterday, we learned why we un-friend someone from our social networks.

According to a new survey, if you're wanting to protect your current group of Facebook friends, these are the top four things we don't want to see anymore in newsfeeds:

  1. Updates about celebrities.
  2. Petitions for social causes.
  3. you've taken of yourself.
  4. Pictures of food.

Additionally, women were more likely than men to use social networks to track down and reconnect with someone from their past, and 63 percent of women in their late 40s have done so.
