[semi-extrinsic]

Oh, this is nothing new.

I remember in like 2007 or something, in the early days of Facebook, someone made a CLI interface to the FB API. And I wrote a random-timed daily cron job that ran a Bash script that checked "which of my FB friends have their birthday today", went through that list, selected a random greeting from like 15 different ones I'd put into an array, and posted this to the wall of person $i. Complete with a "blacklist" with names of close friends and family, where the script instead sent me an email reminder to write a manual, genuine post.

I used to have a golfed version of that script as my Slashdot signature.
