My favorite collection of entrepreneur lectures is from Stanford University’s Entrepreneurial Thought Leaders Series. I highly recommended downloading these from iTunes or listening to them while you work. You can find scores of incredibly valuable lectures here. One of my favorite’s is a recent lecture by Reid Hoffman, founder and Chairman of LinkedIn.com.
The best online collection of interviews with startup entrepreneurs is probably at npost.com. There are 167 so far.
One is a Jan 31st interview with David Sacks, the founder of Geni.com.
