Technology, including social media, serves a useful purpose. In reality, FreeRepublic is a social network. Go figure!
I am on FB and Twitter. Got my parents on FB and it wasn't long before my dad got connected with men he flew with in Vietnam. Best of all, a man who flew out of his based, in a different squadron but during the same time period, lives a few miles away. Finding him and meeting him added a lot to both heroes lives.
Yep, you really must stay away from the evil Facebook. /s
Comparing it to the light bulb is simply utter nonsense.
It is mostly for people to talk about triva aspects about their lives.
And FB isn't at all like FR.
