I deleted my facebook account shortly after being talked into creating it. Why?
1) I started to lose respect for my friends, after watching their drama on FB. TMI.
2) I was being bombarded with small games that were clearly carved out of psychological tests for the purpose of gleaning data about me. Facebook do not have my authorization for obtaining, storing or sharing psychological profiles, whether or not their fine print says so.
3) I've visited their campus and it is creepy, right out of some dystopian novel. This topic is far too complicated to explain here. I'm sure folks must have written books about this by now.
