eBay + RSS + Elvis black velvet paintings = Web 1.5?
One of the benefits of having an open platform means third party developers can push things forward when they want to see new functionality created - and not wait around for it to be pushed out to them.
There are a number of things about this RSS/Atom hack for eBay I like, not the least of which is the author's sidebar about his unabashed fetish for Elvis black velvet paintings that would be perfect in a Tijuana bar circa 1977. This is a developer on a mission.
But my favorite quote lends some interesting context to the Web 2.0 hype:
The Unix philosophy of connecting the input and output of different tools to create new applications (a philosophy that predates the "mashup" Web 2.0 hype by several generations) makes it easy to incorporate Atom technology into existing infrastructures, so you should be able to add Atom notification features to more than just email applications.
