Larry Sanger is an internet project developer and co-founder of the Wikipedia. He's an advocate of freedom of access to encyclopedic information on the net; in particular his latest project Encyclosphere. Encyclosphere is designed to not be controlled by one entity-so Facebook, Twitter, etc can't block opposing views etc-it's more akin to the blogosphere. Larry explains is well in his video here. Pete A Turner and Jon Leon Guerrero's discussion moves fast and covers info discussed in past visits with Larry.
