Today Yahoo! launches a new service called Pipes. It is a interactive feed aggregator and manipulator that lets you remix feeds and create new data mashups in a visual editor. The name pays tribute to Unix pipes, which let programmers chain simple utilities together on the command line. The goal is to let the user create feeds that are more powerful, useful and relevant.
You make a Pipe by dragging pre-configured modules onto a canvas and wiring them together. Each Pipe consists of two or more modules, each of which performs a single, specific task. For example, the Fetch module will retrieve a feed URL, while the Sort module will re-order a feed based on criteria you provide. Once you have built your pipe you can save it and share it the world.
