True, the Forum can get nasty, so I just ignore those folks. But, I have learned some extremely valuable information on the Forum and would be lost without it.
True, Facebook folks all tell their "friends" what they think they want to hear, but I make my own mind up about that too. Besides, when I want a little dose of virtual friendship, I simply go to Facebook and look at all the happy postings and the funny videos to make me smile. So much better than being grumpy...
