On other fronts, Scoble thinks that it would be noble if Google shut down their data centers as a show of support. And Arrington says Bing going to a darker format is like, er, killing baby seals. PS- Did patients on life support die when a San Francisco hospital shut off all its power in observance of Earth Hour?
