Brad Neuberg, Google Gears, and the Future of the Web
Linux.com has an interesting look at Google Gears and one of its leading evangelists, Brad Neuberg. "For Neuberg -- as for most developers -- the idea of expanding the Web's capabilities is intriguing in itself. But both inside and outside Google, his argument is that there's more at stake than just a particular piece of technology. In fact, he does not even seem particularly concerned whether Gears or some rival project takes on the role he envisions. What matters, he says, is that finding a solution to the problems of the Web is essential not only to the continued evolution of the Web, but also to its continued freedom. "
After several years of deployment, Google Maps still displays incorrectly in Firefox 2 if you spin the scroll wheel too fast. That's about where window refresh was at Microsoft Windows 2.x or so - broken.
AJAX is a method to shoehorn functionality into a trifecta of legacy platforms that was never really designed for it. Like retrofitting a horseless carriage with a honda civic engine and bolting on some wings, a rudder, and a propeller with the intent to fly across the atlantic.
Just because you've gotten it to fly doesn't mean you've invented a modern aircraft.
When you don't evolve stuff you have a very good chance to end up with a whole bunch of ugly ad hoc fixes.
