When I first prepared this particular talk… I realized that my usual approach is usually critical. That is, a lot of the things that I do, that most people do, are because they hate something somebody else has done, or they hate that something hasn't been done. And I realized that informed criticism has completely been done in by the web. Because the web has produced so much uninformed criticism. It's kind of a Gresham's Law — bad money drives the good money out of circulation. Bad criticism drives good criticism out of circulation. You just can't criticize anything.
