The Web of documents has morphed into a Web of data. We are no longer just looking to the same old sources for information. Now we’re looking to a new set of tools to aggregate and remix microcontent in new and useful ways.

This article provides an excellent overview on how the web has changed from being a collection of static information, to being a "web" of functionality in which data can be easily seperated from interface. To take an example from the article, Amazon's database is open to the public -- anyone can develop an interface that better suits his/her need for viewing and searching Amazon's content (such as porting the data to a cell phone). This new world wide web is being dubbed the "web 2.0". The article links to two more interesting articles; one on writing semantic markup, and the other on web 2.0 for designers.
