The winners of Washington D.C.'s Apps for Democracy mashup contest were announced by Mayor Adrian M. Fenty and CTO Vivek Kundra. The contest invited software developers to utilize Washington's large public data catalog to develop applications that will make the data more readily accessible and useful for citizens.
ForWhereIAm is a service that offers real-time, short-lived and localised information. Businesses use it as a place to post information they want to share with their customers, and users can visit the site to get information on deals and announcements that are relevant to their specific location. The ForWhereIAm API makes some of this data available to third-party developers.
Have you noticed the many tools to share your location? There's FourSquare and Gowalla, both about a year old. Then there are old-timers like Brightkite. And now, there's one that works with all three (and a couple more).
