If you have been following Defrag from a distance, Sean Ammirati at Read/WriteWeb has an awesome summary up titled Five Themes From the Defrag Conference.
- The Attention Economy
- Next-Level Discovery
- Social Graph
- User Centric Identity
- Enterprise Customers Arrive
In addition just summarizing what was covered, Sean has very insightful paragraphs after each one under the heading “My Take.”
Also, a very thorough summary of many of the sessions was blogged by Charles Knight at AltSearchEngines.
