This is a very good podcast/video and worth the time to watch.
Guests are; Anil Dash who started TypePad with his wife, Sachin Agarwal, CEO of Posterous, and Kourosh Karimkhany, COO of TPM Media.
Very insightful and pleasant.
One thing they talk a great deal about is allowing comments both anonymous or moderated or you have to log in. I found the discussion very open and with a good deal of thought.
