Remember the Facebook "poke" option? It didn't really seem to serve any discernible purpose, other than allowing old high school acquaintances to wordlessly and creepily interact with you. Facebook sensibly removed this function from its front end several years ago. But it has still been lingering in the background, like a smelly, unwelcome zombie.
Nobody was really sure what Facebook pokes were all about, including the company itself. Here's the hilariously vague explanation as it originally appeared on Facebook's help page:
The poke feature can be used for a variety of things on Facebook. For instance, you can poke your friends to say hello.
Note that they only gave one example. This reminds me of the candy lips salesman on The Simpsons:
But anyway. It turns out that the Poke function never really left -- instead, it has been buried off the front page within the additional options list (so buried, in fact, that we originally thought it had been killed off and resurrected -- thanks to all the poke-loving readers who brought this error to our attention.)
If you want to use Facebook like it's 2010 it's still possible to do so. To poke a friend, head to their profile, click on the "more options" symbol and select Poke. Congratulations: you just sent an entirely pointless notification to someone who now hates you.
