David Weinberger keynote:
Enterprise 2.0 is about meta data - information about the information.
When organizing physical stuff, limitation of current taxonomies is that the organizer decides how the physical world will be filed.
It's a sad thing that our information organization skills follow the way we organize our laundry.
Filing systems in the new paradigm:
1. Leaf on many branches
2. Messiness is a virtue
3. No difference between data and meta data
Everything is now meta data. Meta data is the stuff you know and data is the stuff you don't know.
4. Users own the organization of their stuff (tagging, classification, etc.)
You cannot tell what people are going to be interested in.
Knowledge is truly social.
