David Heinemeier Hansson (in London) takes on Eric Ries (via Skype from California) in their first public appearance together, at Leancamp London (http://leanca.mp) on 10 May 2010. They entertainingly disagree on approaches to venture-funded startups, revenue generation and more... (and of course they agree on a lot too!)
I'd like this discussion a lot more if it weren't framed as a clash of two sides. In a debate you're trying to win, but we're looking for the truth. Like Eric says in the video, there's a lot that they agree on. Sure, conflict is superficially interesting, but I think DHH plays it up too much and tried to put on a show. I wish he would have been a little less hostile, it was distracting.<p>To me, the most interesting part was at the end, when they started talking about whether finding a business model is simple or complicated. For some it is, for some it isn't. The discussion they have is enlightening.
