But, a little revisionist about why browser innovation slowed. It wasn't Microsoft yielding to standards demands that slowed their pace; it was Microsoft's de facto victory in (for a time) neutralizing the business possibilities of competitive browser development.
It took a while for alternate models that could sustain further browser evolution -- the Google placement payments to Mozilla, Apple's sponsorship as a complement to their other platforms -- to grow to take the place of the original Netscape dreams.
Hewitt's prescription seems right, though: a bit of healthy disdain for waiting for standards bodies before deploying new things, and some added respect for even those proprietary offerings -- like Flash -- that kept expanding capabilities and user expectations when browsers didn't.
