I originally assumed that Poking was merely flirting: A subtle way to get the attention of another Facebook user. And yet just under half of my Pokes are from males — most of them seemingly straight (or are they?). So again: What does a Poke mean? And should we take a Poke to be flirtatious when it could, in my case, just as easily mean “Hey, I just sent you a press release about my new app”?

Facebook doesn’t even know what a Poke means, with the Help page reading: “The poke feature can be used for a variety of things on Facebook. For instance, you can poke your friends to say hello.” Ah, so they’re either saying hello, or flirting, or pestering … or something completely different.

via Facebook, It’s Time To Kill the Poke.
