I have a hard time asking questions and running the camera at the same time. (Sort of like reading and walking, maybe). When I have a camera person I'm able to think better.
I do think we should open things up a bit and let you know when we are going to interview somebody interesting and give you an opportunity to put forth some questions that we should ask. In the end, Scoble and I just don't know everything about our technologies.
We're learning too, in realtime, just like many of you. That said, you'll find I do much better when the topic is closer to my level of knowledge and or personal interest (read CLR, Windows, Security, competitive platforms, bourbon, wine, cigars, oh...)
