For years I have been advocating the benefits of progressive enhancement as a safeguard to deliver working code to the world. In this – my final public talk as a full-time Yahoo employee – I talk about the why and how of progressive enhancement. I take a look at examples from the real world and point out dangers of repeating mistakes from the past for the sake of showing cool technnology.
There is also a copious amount of swearing if I remember correctly. Enjoy.
