Hey HN, I actually made this site as a companion to my RailsConf talk yesterday (I'm sure it was humorously confusing out of context).
The talk's slides are up here: https://speakerdeck.com/searls/sometimes-a-controller-is-jus...
And video here (better versions coming soon): https://youtu.be/LdWMcs9EEOE?t=2h56m
Humorously I joked about it hitting HN during the talk, and then it actually did. We as developers can't resist something that'll quantify for us whether we're good at writing software, even when we know it's flawed.
