What should I ask Daniel Gross?

I will be doing a Conversation with him, noting that he is my co-author on Talent: How to Identify Energizers, Creators, and Winners Around the World.

Daniel is an entrepreneur and venture capitalist and here is his Wikipedia page.  Here is Daniel on Twitter.  Here is Daniel’s ideas page.  Here is Daniel on his work, including Pioneer.

Since we are co-authors, this won’t just be the standard interview format, how do you think we should do it?  And what should we ask each other?
