Yahoo said over the weekend that it was opening up its market-leading mail service technology in order to allow developers to innovate on top of the service and build new applications. The move is called one of the largest code giveaways ever.
What is being given way is the browser-based authentication scheme for Yahoo Mail. This would allow developers to build new user interfaces or methods to display a user’s incoming mail. Yahoo says it cannot create all the applications users want; thus, opening up the code was a logical move.
