In a bold move on Friday, Yahoo! announced that it will be providing the API code to Yahoo! Mail, an action that they hope will enable developers throughout the world to create new services and addons to its popular email software that is used by over 257 million individuals.
Yahoo has already provided such access to the public in providing the code to its Flickr software, and Google Maps also allows development on its platform. The OnNYTurf NYC Subway Map is based on this code.
