I’d never even heard of Identity 2.0, but I was sent a link to this presentation from one of the email lists I belong to. It’s an excellent presentation, showing simplicity, and good use of graphics to go along with a presentation. This is how presentations should look. Even if you don’t agree, or don’t like the particular pitch, the presentation itself is worth watching.
