I was there yesterday. Gave a talk at the Web 2.0 open and spent the rest of the day listening to talks, catching up with friends. The talk that I enjoyed the most was David Hornik’s presentation: What I Learned from Syphilis: Epidemiology & Viral Marketing. The talk was about how to apply lessons from successful viruses to web apps. David is an engaging speaker and his approach made you think about the problem of virality of web apps from a different angle.
Some of the presentations (listed below) are starting to show up on SlideShare as part of the SlideShare Web 2.0 group. The ones that I see so far are
Thomas Vanderwal: Tagging that works
Kellan: Casual Privacy
Steve Souders and Tenni Theurer: High Performance Web sites
Andre Charland: Web usability for the rest of us
Thomas Howe: Writing voice mashups with Amazon Turks
and my own of course
Please add yours if you did upload to SlideShare (or anywhere else for that matter).
I read some the presentation slides. Nice material you have and great ideas.
Hope that more and more Web 2.0 Expo presentations will show up on SlideShare.
