A presentation given by Breandán Knowlton (@bfk) at the "Ready to Inspire" conference held in Leiden, The Netherlands on 10 Dec, 2012 (http://2012.inspireconf.com/). Matthew Pennell posted some notes at http://www.thewatchmakerproject.com/post/ready-to-inspire-breandan-knowlton-bridging-the-gap-between-designers-and-clients/.
The essential take-away is that the tools and processes of web design support a state of "flow", and that projects can be designed in a way to include clients in this state, leading to greater engagement and better, more meaningful projects.
