As promised, here is the podcast that Ben and I recorded this morning. It runs just shy of 17 minutes.
One note: In the recording we mention that the Attention Trust sells attention data. I believe this is incorrect in that they offer a service for storing your own attention data online but do not sell that data. What benefit this offers to the individual is unclear to me. Maybe Ed Batista can chime in here on the comments on what benefit you would receive from loading your data into one of their providers.
