Structured data has an open platform, thanks to a new startup aptly named Factual. At first glance, it seems like Excel on the web. However, Factual is more database-oriented, with joining and filtering built-in. Plus, sharing and discussing the data is an integral part of the experience. Most functions on the site, including both reading and writing data, can also happen via the Factual API.
Bryan Parker founded ImageFly out of necessity: "To be honest, I was fed up with having to bounce around between image libraries when I was hammering out a project. It seems like it was GD one day, RMagick the next, and something else the next." ImageFly exists to simplify image modification. The ImageFly API grants developers many image editing tools within web properties and applications.
