Yahoo Pipes
ahab_2001 writes "Yahoo has introduced a new product called Pipes. It seems to be a GUI-based interface for building applications that aggregate RSS feeds and other services, creating Web-based apps from various sources, and publishing those apps. Sounds very cool. TechCrunch has a decent write-up, and Tim O'Reilly is all over it. The site was down for a few hours and is just back up. Has anybody tried this?" From the TechCrunch article: "Pipes is... akin to a shell scripting environment for the web rather than just a simple conduit between applications."
The concept sounds very similar to QEDWiki demo video (demo video requires Flash).
QEDWiki is an IBM product based on the Zend Framework. You can create mash-ups and other things much like by drag and drop of components, all in your browser.
