Calling the interviews chit-chat is nothing short of demeaning the effort of both Andrew and the interviewee. I would argue that the interviews are great and do teach us a lot. Often as part of the interview other parts such as history are covered, but that again adds to the whole experience.
Finally, the reason I believe this will not be a blockbuster, is because of two reasons.
1. On the net people rarely pay for content. 2. Scrappy entrepreneurs by my guess, are not the ones who would fall in the category of "paying people".
I do hope that Andrew is successful though.
