A huge number of drug dealers start off just being drug users, then start selling to a friend or two, then realise that given they're already getting hold of the drugs, and kind of almost dealing already, it might be a good way to make money. I've never met someone who called himself a dealer who didn't take drugs himself.
I don't know anything about the poster or his relationship to Zuckerberg, but there is probably a built-in alert for mentions of Zuckerberg. Else unless they're friends, how would he see this within 6 minutes? If I had a Facebook account, I'd append "Zuckerberg" to every post, just to dilute the signal with a little noise.
Correct. I am friends with Kelly, who works at Facebook and is friends with Mark. She replied. Her activity on my status update would have made it appear in his newsfeed.
Kelly and Jeremiah appear to be friends. Kelly works at Facebook and explained she had Mark's stories in her feed, so it seems reasonable she is friends with Mark and he found out that way?
nobody says he sits there monitoring any update with his name in it. just that he probably has a system set up that allows him to monitor it should he choose to.
