If you want to understand the potential of this medium, go see what Ta-Nehisi is currently doing over at The Atlantic. As he researches black history and civil rights in America for the sake of writing something longer on those topics, he’s taking a tour through the social contract tradition and his readers are tagging along for the ride. They agree to read a chapter of Leviathan each week, he posts some thoughts on Friday, the comments section grows and then key reader contributions are flagged. Everyone involved in his online community learns something. Philosophy is made digestible for people through digital interaction without any multi-thousand pound degrees and institutions being in sight.
