Hi,

Nope, stack overflow didn't invent Gameification.
This was already quite fun:

IEEE Guide to Classificaton of Software Anomalies
https://github.com/Orthant/IEEE/blob/master/1044.1-1995.pdf

Here some examples:

- Boing Airplane lost in the Maledives:
   No problem, severity 7

- Salary Payed twice by Booking Software:
   No problem, severity 0

LoL

Bye
