"The Saddest Thing You'll Read All Weekend" aka "Facebook Explains Gravity."
I don't have a Saddest-Thing-I-Ever-Saw category, but maybe I'll have to consider adding it...
Y'know those STAR TREK episodes where the Enterprise comes upon a civilization with a decent to sophisticated level of technology but an infrastructure that's falling apart and a scantily clad populace that has no clue how to maintain it (or adjust the collision course of their world-ship, or reprogram their artificial intelligence caretaker-turned-god) because over generations its citizens have taken that tech for granted and allowed the science and knowledge behind it to fade into forgotten history?
This is how it begins.
Keep on keepin on~
