Cut and paste with Pipes...

...Newsfeeds have been around for a while. Now Yahoo has a new project called Pipes that "is an interactive feed aggregator and manipulator. Using Pipes, you can create feeds that are more powerful, useful and relevant." For example you can create simple mashups of tech sites and clone and custom other Pipes. It is a GUI-based interface for building applications that aggregate RSS feeds and other services, to create and publish Web-based apps from various sources. The site works by letting users "pipe" information from different sources and then set up rules for how that content should be modified (e.g. filtering).
