This app demonstrates a site can log in users, and fetch their Yahoo! profile data, with OpenID (incl. Attribute Exchange) + OAuth hybrid auth. User's are also able to simply authoriza access to data using using OAuth. The end result for either action is that the user's name and profile image are displayed. The app serves as a way to compare the OAuth and Hybrid auth implementations.
