I was on Facebook, and it had a big upside--keeping in touch with relatives, hearing about concerts, and so on. But it really sunk in at one point that the whole magilla was a trap and a tool of control. I quit about eight years ago (took the compressed file with me) and never regretted it. I have found other time-sucks to take its place.

I will miss the ease of keeping up with relatives.
