KudoStar is a mobile social rating system that connects your contacts and favorite (or least favorite) locations.
People and places accumulate positive and negative Kudostars (known as "KudoScore"), with relevant sound, images, and video while keeping the user interface intuitive and simple to use. KudoStar then uses this information and ties it in with not only other Android phones but also your social networking sites.
KudoStar will also utilize Facebook's F8 and Google's opensocial platforms to virally spread the collected data to a multitude of users. Tying Google Maps, and v:social's media platforms KudoStar will allow a vast array of viewing options for the data that is collected.
KudoStar is currently still under development and expect a public alpha in the near future.
More information on the current state of the project may be obtained from the KudoStar project's homepage.
