I’m a bit late in posting this, but I think it’s worth it: An August 12th tweet from Spencer Fry, the young developer of Carbonmade, which he calls “the largest online portfolio website” around. (Mine is among the 250,000 portfolios.) His tweet brings to mind a quote I read last week in the New York Times. “Everything I’ve ever organized, I’ve run through Facebook. I’ve never spent a cent on advertisements.” That was from Rob Bliss, who’s organized a dozen public events in Grand Rapids, Mich., the most recent being a 500-foot-long water slide stretching three city blocks.
