  1). iTunes and TiVo also demonstrate many of the other core principles of Web 2.0. They are not web applications per se, but they leverage the power of the web platform, making it a seamless, almost invisible part of their infrastructure. Data management is most clearly the heart of their offering. They are services, not packaged applications (although in the case of iTunes, it can be used as a packaged application, managing only the user's local data.) What's more, both TiVo and iTunes show some budding use of collective intelligence, although in each case, their experiments are at war with the IP lobby's. There's only a limited architecture of participation in iTunes, though the recent addition of podcasting changes that equation substantially.
