Yahoo! is opening up to developers using Web services. Today our services enable developers to access Yahoo! properties as diverse as Web search, maps, Flickr, comparison shopping, and many more -- and we're making more available all the time. In this session you'll learn how you can incorporate Yahoo! Web services in your application or Web site, and see a demonstration of integration between Yahoo! Web Services, the new Yahoo! Presentation Library, and ASP.NET "Atlas".
