DHH vs Eric Ries at leanca.mp in London 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!) 3 comments
