The workshop had a panel discussion "Models for Sponsored Search: What are the Right Questions?" organized by Rakesh Vohra and yours truly. Panelists were Kamal Jain (Microsoft), David Pennock (Yahoo!), Michael Schwarz (Yahoo, UC Berkeley) and Rakesh Vohra (Kellogg School at Northwestern). The panel was moderated by Jason Hartline.
Jason recorded the discussion which I converted to MP3 (98 minutes, 17 MB).
