This is fascinating for many reasons. For one, I've never seen Steve do a talk on primarily developer technology.
Yeah, it is pretty cool. It is amazing how much thought has gone into the concept of dynamic web pages and building that technology back in the days when the internet started getting popular. We take it for granted these days.
I found it especially interesting to listen to the concerns from the audience in the Q&A at the end. We have come a long, long way.
It's interesting that Steve was using the 99 designs format before 99 designs was even an idea.
