I listened to the show, it was pretty good. He could not answer some of the technical questions about Steemit but he explained he just started a few days ago.

You should try and get Dan and Ned on the radio show. There is a lot of technical information on this multi-layered system that provides both security and longevity to its users. This is a very important aspect of the platform in stopping hacks and other types of security attacks. This is also what it makes it better than all the other Cryptocurrencies.
