To summarize, the talk argues that lower barriers on media publication increase the abundance of media and the importance of attention. We need tools that surface what is relevant and interesting, that help people find what they need.
I particularly liked slide 54 on smart aggregators:
The Aggregator 2.0And slide 57 on reconstructors:
Allows consumers to navigate complex media landscapes by efficiently allocating scarce attention according to preferences and expectations
Leverage deep information about content to predict utility derived by consumers, slashing search and transaction costs of consumption
Examples:Collaborative filtersSmart aggregation is aggregation of content plus aggregation of information, expectations, and preferences about content
Recommendation & rating systems
Similarity & difference filters
The Reconstructor is the aggregator 3.0See also Scott Karp's summary of the talk.
Deconstruct micromedia by altering, remixing, and filtering microchunks to reconstruct 'casts of personal media ... [For example,] blog entries from individual blogs, tracks from individual playlists
