This is a really good talk. People give these advice talks about creativity/innovation etc. all the time, but this one by Jack Dorsey (twitter inventor) is absolutely worth the time. really got me thinking. He's a real inventor. His newest idea is pretty awesome as well.
It also reminded me of the Library Hose. Not because of Twitter (which is the broadcast channel for this), but because it was an idea that we did a while back and kinda shelved. And now its coming back around into ShelfLife.
