Yahoo's plan to move the company forward involves much more than just search, and as such the company has decided to host their next Open Hack Day in Taiwan later this year in September. The event is an attempt to spur development using Yahoo's own APIs, encouraging developers to publish a web-app as fast as possible, doing all the development in a single day. Their goal is to further the Yahoo vision of a massive social platform, which they are dubbing the Yahoo! Open Strategy.
Yahoo-sponsored Hack Days have been happening since 2005, and the idea has spread to spawn other events as well. A lot of code might live and die in the few days the events take place, but the hope is to generate interest as well as fresh ideas which could give Yahoo the boost they need today.
