For my money, the biggest online developments this year were podcasting and vlogs. Anyone can create and distrubute media, globally, for free. Pretty big deal I’d say. iTunes support of podcasting and videoblogging was of course a huge boost to bringing media-casting to the mainstream. Does that qualify as Web 2.0? I don’t think iTunes itself qualifies, but rich services such as Odeo and Mefeedia are innovative and user-driven – tasty Web 2.0 qualities.
