Well... I have been interested in Wiki's for the past year as an interesting paradigm, that needs some help, but form a groundwork for a larger idea... the mother of all databases for everything that ever is, was, or will be in any of our heads.
Wouldn't it be nice to be able to just use a device that is geared toward wiki use as a personal data assistant (pda) application that interfaces with the wiki markup in a handwring interpreted manner for a pda app? Wish i new a programmer that liked this idea... because the web we know it today needs to pipe to secure personal applications that are used a permissive and thus subscribable userbase for like $1.99 a month... (hense $$$ for future innovation.) or maybe a brain fart... not sure yet.
