This talk addresses the accessibility strategy at Yahoo! and demonstrates several production site examples of how Yahoo! used content from other Internet sites, such as Facebook, Twitter, BBC and Discovery Channel to build fully accessible applications for the Yahoo! home page.
One of the highlights of Web 2.0 is the ability to aggregate and mash the content from one or more data sources and present it elsewhere on the Web. While many kinds of data transformations are possible in this way, it is the presentation aspect of content aggregation that attracts many designers and developers to the idea. For example, an interface that was not designed with assistive technology users in mind can be transformed into a fully accessible one by extracting the original content from the data source and building the new interface on top of it.
