Ribbit announced a potentially lucrative new contest called the $100,000 Killer App Challenge. This contest will award $100k in prize money to developers in five categories who submit applications that use Ribbit technology. This is a great opportunity to build an application using Flash, Flex, and/or Adobe AIR that not only shows off your developer skills, but also presents the chance to put a few dollars in your pocket.
Daniel Dura, a platform evangelist at Adobe and one of the judges for the challenge, has additional details on his blog as well. Be sure to read the official rules and regulations to make sure that you qualify.
