At Openbeta3, I gave a presentation on doing a web-based startup in Oklahoma City. We had 5 minutes and 20 slides, one every 15 seconds. This was my first talk in this format. It was a bit rough, but fun.
This is a great interview with Kevin Rose of Digg.com. It starts out with a bit of history of how Digg was in the early days. It follows with a history of where they are now. The interviewer is able to get a few bits of information about where Digg.com will go next. The interviewer is a bit annoying.
This video gives a bit of insight to a well established company and how they got to their current condition. I think it is a good history lesson on Digg.com.
