All Design is Redesign

I'm exploring website redesign, specifically with an eye towards end-user redesign. With increasing hordes of diverse people, devices and activities having virtual presence, leveraging motivated/power users to redesign existing systems for specific devices/uses/communities/etc may improve the interoperability between them.

Many proponents of web services suggest that 3rd parties will fill various niches if/when given programmatic access to an existing system. My instinct is in a similar vein, but requiring something less than "software engineer" level skills to play.

Here is an example of the bay area transit trip planner ( http://transit.511.org/tripplanner/index.asp ) redesigned for small-scale devices, like mobile phones -> http://liquidcycles.com/trip

Try it out -- what works/doesn't?
