Clay Shirky explains why collaborative filters should be revolutionizing the music business.
This is all part of the Big Flip in publishing generally, where the old notion of "filter, then publish" is giving way to "publish, then filter." There is no need for Slashdot's or Kuro5hin's owners to sort the good posts from the bad in advance, no need for Blogdex or Daypop to pressure people not to post drivel, because lightweight filters applied after the fact work better at large scale than paying editors to enforce minimum quality in advance. A side-effect of the Big Flip is that the division between amateur and professional turns into a spectrum, giving us a world where unpaid writers are discussed side-by-side with New York Times columnists.
The music industry is largely untouched by the Big Flip. The industry harvests the aggregate taste of music lovers and sells it back to us as popularity, without offering anyone the chance to be heard without their approval. The industry's judgment, not ours, still determines the entire domain in which any collaborative filtering will subsequently operate. A working "publish, then filter" system that used our collective judgment to sort new music before it gets played on the radio or sold at the record store would be a revolution.
