Good to hear more coming Rick.
Regarding more detail, let me start with this. Ethan has adapted well to the new media. He has obviously developed a method or style, of interacting with the YouTube "trade show" interview. Since I know Ethan monitors most post here, I'll say it directly... Ethan you have done a brilliant job of delivering the information you want to communicate, regardless of the interviewer. You do a great job of doing what you can to make the interviewer look good. It serves you well, it serves them well.
The challenge for the interviewer then becomes producing something that is different than previous videos. Otherwise, for the viewer, it's the same story with a different face next to him. Does that make sense? The interviewer needs to ask questions that lead Ethan into stories, or philosophy, that the audience hasn't heard. I learned and use a technique for presentations that I think might apply here. " Tell them what you're going to tell them. Tell them. Tell them what you told them." In this case, you might consider opening the video with just you teasing what's to come. Then the interaction between you and the guest (in this case Ethan). Then close the way you opened and recap the most interesting, important, information from the interview, along with your analysis, one on one with your video audience.
I can't imagine Ethan ever leaving somebody hanging with simple yes or no answers. I've seen a lot of video with Ethan. He's a dream with unlimited anecdotes. You two have an obvious rapport. I'd like to hear more about the over 20 year development of the BK20. How did timing play into it's production and it's likely success? What experiences led to the developments and design refinements? Does the introduction of the BK20 change the marketplace? If so how? And of course, what can he share about the future of the BK20 and what if anything might be developed as a result of it.
I hope my observations are useful to you Rick. Keep up the good work.
