The past year has seen a dramatic change in how developers build web applications, and how consumers use them. Using the network as a platform, cutting-edge consumer applications no longer content themselves with being stand-alone static HTML sites, but instead have become far more dynamic: consuming and remixing data from multiple sources and rendering this data via rich user interfaces. 

But while how we "play" online has changed, how we "work" on the Web has remained stuck in traditional development and delivery models, leaving our living rooms often more advanced than our offices.  Fortunately, the technologies underpinning "Web 2.0" are starting to change expectations about how business applications are used and built. Just as RSS, open web APIs, and AJAX have emerged as well-understood parts of the consumer Web, so these new technologies promise to revolutionize how companies work, how they are run, and how they distribute and consume technology and information.

AppExchange, salesforce.com's new application building and sharing service, provides a platform for developers to use these new technologies to create on-demand applications that deliver innovative services to businesses. This session provides a technical overview of AppExchange, the salesforce.com application development model, and examples of how the platform can be used to "mash up" services across the Internet to create compelling new applications.
