The keynote was by a guy from Threadless.
Threadless sells clever, artistic T-shirts.
The company has lots of culture. It's very hip.
The designs are community driven. The community votes on them.
They don't actually print the shirts themselves.
Threadless is in Chicago. Rahm Emanuel visited. After he visited, he Twittered, "Seriously, this city used to build things. Now we're just assholes with novelty t-shirts. I'm with motherfucking stupid."
They switched from PHP to Django. They're still fighting a lot of technical debt.
Threadless is an "art community".
The speaker was hilarious.
