What the web needs is a UI demo site. You could submit a page that was a demo, and it'd have some metadata in the markup to describe it, and then that would be iframed into the site - then there'd be a header to navigate all the demos. It could be called UIpalette. Any takers?
how's this compare to something like touchscroll.js for reproducing native-style scrolling in a mobile web app? e.g. content div that scrolls with fixed footer on ios
