Yahoo said over the weekend that it is now opening up its market-leading mail service technology in order to permit developers to innovate on top of the service and also to build new applications. The move is called one of the largest code giveaways ever before.

This will surely allow developers to build new user interfaces or methods to display a user's incoming mail. Yahoo says it cannot create all the applications, which user require; thus, opening up the code was a logical move. This service is accessed by more than a quarter of a billion Internet users worldwide says Yahoo.
