I'm surprised Tobis didn't include Fred Pearce in his little Broderite grouping. BTW, I'm just a piker compared to Revkin (and Pearce), both who are far more distinguished than me. Speaking of Pearce, a Bishop Hill reader provides a nice dispatch of a recent Pearce lecture at the Royal Institution. As for the Jay Rosen meta post (which he is famous for) that Tobis references, count me in the This is complicated! camp.
