I live in Los Angeles, CA. My friend who lives and works in Washington DC announced on Facebook that she has a new Twitter account name, so I entered that into the Twitter Find People feature, and followed her. We otherwise were Facebook friends, but I had not been following her on Twitter.
Within minutes, my email showed that she was following me, too. We exchanged Direct Messages. I told her I barely ever used Twitter to announce what I was doing, but preferred to use it like little emails, just for Direct Messages.
My cousin Steve also lives and works in DC. She wrote back the following: “Your cousin Steve (I think) was my Mac instructor the other day. How do I know? We were in my email and he saw you sent me a message.” I immediately thought: The Odds Must Be Crazy 🙂
[EDITOR: The same thing happened to me last week. Only instead of Twitter it was on <CENSORED> and instead of my Mac instructor it was my <CENSORED>. But otherwise exactly the same.]
