I had over 300 friends on facebook. Now I am down to 50 (family only and people I actually see now and then) and even at that, I ready to delete my account.
My reasons were far less involved, though. It just felt like one long, never-ending high school reunion. (GAG) People posting about their perfect kids, perfect husbands and perfect vacations.....
I also learned far too much about the political views of friends and family. My own mother "liked" Sarah Palin AND Beck.
Course, maybe I could have changed my perspective of it all and had a more positive experience, but in the end, I prefer real life and I don't miss knowing what my friends from twenty years ago are up to....
