If you’ve heard of Hack Day before, you probably know that hack days are usually just for Yahoo! employees. But this time the event is a wide open, public hack day where people with a passion for Yahoo! products can come together to build and share their best ideas for extending, re-shaping and mashing together our products and features. If you are interested in particpating you can still sign-up for a Hack Day invitation by visiting http://www.hackday.org.
