I stopped in at Thingamajigger Friday night, it was great! John Medina effortlessly held the crowd’s attention while he talked about attention, Dan Savage told us how tech has ruined his life, I talked to Hazard Factory’s Rusty Oliver about optimum sanding belt grit size for the best power tool drag racer traction, Beth Goza explained Knitting 2.0, and Simon Winder told me about his Ionization Clock.
