Twitter real-time search is starting to spawn various sites and services that are finding interesting ways to use the data that Twitter makes available. We Are Hunted has a new extension of their trending charts (they already track p2p, blogs, facebook, forums, myspace) for the top 99 tracks being tweeted about on Twitter. A visual interface, streamlined player and “click to buy” feature make for a simple discovery site. What excites me most is that the emerging real-time web is unlocking all types of new discovery options.
