I almost forgot about this, but recently Yahoo launched a new service called Pipes. It's a drag and drop interface which allows you to combine several feeds into one. Remember how much time you'd spent to read every single feed subcriptions. With pipes you can actually combine your favorite feed and categorized it as a theme (News, Tech, Gizmo, etc) you just name it.If you look inside the pipes you must agree with me that to build a pipes it is not for a faint heart. But once mastered, you can build as many pipes that you want with different purposes. For example, did you ever wish to monitor eBay price that match your budget? Pipes allows you to build query from a base feed url and set rules or filter before streaming it out to the pipe output. Take a look on my simple pipes. It translates a feed into a different language.
I thought saw one or two blogs refering Yahoo pipes as a web 3.0. Looking at pipes capability it's definitely a next generation of web application. In this new era, manipulating a web 2.0 application is the next challenge and Yahoo! pipes succeded.
