If you came to NTC 2005 in Chicago, you probably remember Esther Dyson, and you either loved or hated her (I remember the evalutation forms very clearly!). Well, she's bringing her market-centered thinking to the latest nonprofit debate about certified email. This Thursday, Mitch Kapor (another favorite rabble rouser of mine) will be moderating a debate between Esther and Danny O'Brien from EFF. The event is an EFF fundraiser hosted here in San Francisco. Get more details and learn how to attend.
