Microsoft's Bing has launched a private preview release of two new Bing Maps APIs. The Bing Maps Location Recognition API and Bing Maps Autosuggest API allow developers to deliver new kinds of experiences and provide richer analytics about locations at which users are situated.
I generally cover shopping related APIs, but recently hackathon events have piqued my interest. This past weekend I attended a two-day hackathon called “Reinventing Local”. This event was hosted at General Assembly, a local co-working space for startups in NYC, and well-known in the entrepreneur community. The theme was geared toward local businesses and was presented by American Express OPEN Forum, which I feel necessary to mention now has an API of their own allowing instant access to small business content. The event was sponsored by Mashery (also a ProgrammableWeb sponsor), ConstantContact and Meetup.
