Chris Anderson links to a video he uses in his talks:
For the past year or so, I’ve been ending many of my speeches with this brilliant video by Peter Hirshberg of Technorati, and Michel Markman. They showed it first at at the D conference last year and a few times since then, such as the EG conference earlier this year. Now Michel’s uploaded it to YouTube for everyone to enjoy. Some of the lines, such as “There are a lot more of them than there are of us” and title of this post, are now permanently lodged in my brain. Thanks Peter and Michel!
Take a look!
