The Thursday Tech Talk after Thanksgiving is the day before the Prediction Markets Summit we’re co-sponsoring with Collabria. We’re taking that opportunity for a dress rehearsal of Chris Hibbert’s opening address, Zocalo: An Open-Source Platform for Prediction Markets. We’ll also preview some of the other speakers and subjects expected for the next day’s meeting at UCSF Mission Bay, as well as peripheral discussion of another upcoming PM event in December in London
