I just discovered that my keynote at the 2o10 NODEM conference on digital media and heritage is available online. If you're into video, check out this 25 minute talk I gave on the conference theme "from place to presence." I focused on three surprising things I've learned about design for participation both in physical spaces and on the Web:
the importance of constraints and scaffolding to supporting creative and social participation
the role design plays in driving how people participate
the essential necessity for the institution to be responsive to participants
If you want to download the slides, they're here. And if you want to see other NODEM talks from Fiona Cameron and Michael Edson, they're here.
