Audio podcast - worth a listen - I like the concept. MediaBerkman, Berkman Center for Internet & Society Audio/Video Podcast, Messiness as a Virtue:

David Weinberger hosted another evening in his Web of Ideas series. This week’s topic is “Messiness as a Virtue” — an open discussion on the importance of orderliness in knowledge.

His blog. And a post ‘Web of Ideas: Messiness as a virtue’, with comments on the presentation.
