It seems like every day I learn about some new, uberbrainy conference that I can’t afford to attend and aren’t smart enough to speak at, the most recent being Supernova. Supernova is all about “how decentralization and pervasive connectivity are changing our world.” Mitigating my frustration is the fact that many of these conferences are now publishing their proceedings online (to name two biggies: TED and SXSW). Supernova’s got video too. Don’t miss Clay Shirky, always a healthy dash of common sense for our collective moments of irrational exuberance. [oreilly radar]
