del.icio.us adds filetype tags automatically to media files.
I could go into boring things like implicit metadata, the coupling of a flat tag pool with a flat:hierarchical:organization... but really, there are more fun things that come out of this.
Like, for example, discovering a spoof of the ending of the movie Se7en involving The Shat brilliantly playing himself in three roles, a stunning demo video from inside Sony's computer sciences lab of some futuristic UI (especially cool is the "hyper dragging" in the closing seconds), and Triumph the Insult Dog unleashed (hehe) at the Michael Jackson trial.
Who needs TV?
Who needs radio?
