Can you defend against a zombie apocalypse by tracking achievements?
Amidst constant rallying cries of “Awesome!” and some genuine (and some ironic) high-fives, we planned and built most of a website for keeping tracking of how you're doing against your goals. We also planned how to survive a zombie apocalypse.
In the end, Keep Being Awesome never launched; although we had a lot of fun making it, we never quite cracked how the achievements should work. (We did finally launch something a little bit similar, with smaller scope, as Be Habitual, built in /dev/fort 7.)
