My wife is a facebook "enthusiast". She nagged me to sign up. I let her enroll me (since she is the expert). Two days later I started searching websites that detail how to get free of farcebook. The next day I burned my account and have not gone back. To me farcebook and the rest of the "social media" was/is/are:
1) Another point at which various nitwits and losers can impact my life.
2) A video game for people who can't shut the !@*# up.
3) A diversion for those who believe that having a lot to say is the same as having something worth saying, and who enjoy publicly manifesting their ignorance. An English Army officer once said of another officer "He treats stupidity as if it were a virtue." Not everyone I met on f-book fits this description, but enough did.
The damage to our society from such nonsense far outweighs any benefit. I can only hope that there is an especially deep, dark, hot place in Hell for those who create these things.
