Yahoo's mobile development initiative, led by Ricardo Varela, introduces Blueprint, an open platform aimed at maximizing app distribution through a simple XML framework. The objectives include enabling apps to function across multiple devices with minimal effort required from developers while ensuring a high-quality user experience. Current efforts focus on expanding support for more devices, carriers, and widgets to enhance integration and monetization opportunities.
