Yahoo! Pipes looks like a product that could change the way web designers and developers consume and user RSS. Pipes are a familiar terminology if you have ever done any Unix command line work. Pipes in Unix-land allow you to route the output of one tool into the input of another tool. The pipe character | is used as a separator between each command. So what makes Yahoo Pipes revolutionary? Well to start it provides a drag-and-drop interface that allows you to connect RSS feeds from multiple sources and perform operations like sorting, counting, and grouping. And it does this without requiring the developer or designer to write a single line of code.
