Great quote that ties in with the discussion about Sergey Brin's observation (blogged on BoingBoing at http://boingboing.net/2002_12_01_archive.html#90036239) that failed search-engine companies were run by execs who didn't use the net:
"Telephone companies could [cannibalize their own products to beat competitors to the punch] too, but it is unlikely as long as their senior managers prefer to talk with lawyers, regulators, consultants and financiers more than with experts in their own employ."
