TagCrowd - make your own tag cloud from any text. Nudge:nudge. So Del.icio.us! Intelligent Tagging for.

It was designed to be a "large-scale outboard memory," with added sharing smarts. It works like this: you take all your digital stuff--mainly URLs now, but color definitions and audio files have found their own special homes on the site too--and throw it into your del.icio.us account. Thanks to tagging and searching, you can find your stuff easily later.
