We've opened up Yahoo! from the inside out with our world-renowned Hack Day, and from the outside in through the Yahoo! Developer Network. Now we're opening up Yahoo! itself to a select group of hackers and special guests for a weekend festival of hacking, camping (yes, the tents-in-the-outdoors kind--we have really, really nice grass!, music, and good times.
The event is Friday, September 28th, if you are a developer who has an idea for a project it is well worth attending.
