I also noticed people tend to get de-socalized, take this scenario for example.
P1: Hey how's it going?
P2: Read my Blog?
P1: Why? What's up.
P2: Just read it, it says.
I was just out with some people I know recently, and one of them was starting to tell me about this performance thing he had done. He started to tell the story and I say "I know". He looks at me, totally bewildered. "How?" he says?
(we hadn't talked since way before the event)
"I follow you on twitter"
Ha ha ha He stole his own thunder.
Really! Why post stuff on your feed if you dont expect people you know to read it?
