His main points:

• The shape of business is changing … authority, trust and boundaries.
• Why aren’t we drowning in information overload? Because the answer is more information … particularly meta-data, which is what Enterprise 2.0 is good at.
• In the physical world, you can’t have two separate things in the same place at the same time. Someone has to make decision as to who goes where. Eg, newspaper columns, org charts. Very tree-like structures. The problem is that this way of sorting is that you have to pick one place to put things.
• In the digital world, these distinctions don’t work. We’ve assumed the limitations of tree-like structures, but we don’t have to. In this third order … (a) a leaf can go on many branches, (b) messiness is a virtue because it enriches online, (c) there’s no difference between data and metadata — everything is metadata, because metadata is the stuff we know when looking for what we don’t know, and (d) the order is unowned — by owners, but is instead owners by users.
• So … the historical way to order organization was to get experts to come up with a way of doing the organization. It worked in the physical world, but it doesn’t work in the information world.
• You can’t tell what people are going to be interested in … so we need to give as much as possible.
• Broad implications … authority, trust and fallibility (Wikipedia has a way of highlighting fallibility, which makes us trust it more).
• All of these changes are major and significant. It’s not hype.
