detailed description:
It is a common situation in the software realm to find out that there are a few "best applications" in a given category - all of them have some terrific features, but none having them all; usually x has what y does not have so a user may end up in need of both products.

While having an ideal have-them-all-features-in-a user-friendly-interface is nearly impossible to make, it is not a bad thing to strive for one. GS can help developers strive for one easier by opening what I can image as "the ideal application wiki feature list". For example: a wiki for the ideal browser to which users would contribute all the features that the ideal browsers should have. And so on for any other category of software. (Maybe the best caegories to start would be "the ideal wiki farm" or "the ideal community support platform").
