If 2004 was the year of the new search engine and 2005 the year of tailored search, 2006 seems to have been the first year of Web 2.0. Interactive, participatory Internet activities such as blogging, podcasts, online video sharing, and wikis dominated the discourse.

Many websites now serve as directories to help users find podcasts of every variety anywhere in the world. Podcasting has caught on because it is easy, inexpensive, mobile, flexible, and powerful.

Another important aspect of Web 2.0 is that it organizes information differently from traditional web and other news and knowledge models. So reports a Time article on the frontiers of search in its 5 September 2005 issue. There is good reason to believe this claim, given a major investment firm's assessment that "by 2010, search-engine advertising will be a $22 billion industry worldwide, up from an estimated $8 billion today."

One casualty of Web 2.0 appears to be directories. are hierarchical guides to a subset of what are presumably the best, most relevant (or at least most popular) websites on a specific topic. Yahoo was always the king of directories, but 14
