Yahoo! unleashed its new product : Yahoo! Pipes. As John Murrell wrote for 'Good Morning Silicon Valley' :
"Pipes is a tool that lets the average user build easily what programmers have been hacking together for a while: Custom combinations of the RSS feeds now nearly ubiquitous across news sites, blogs and other information services."
Used together with widgets, Pipes is going to be the fundamental brick for the forthcoming revolution in professional custom apps, built by the end-users for the end-users. Thanks to Pipes, you will be able to aggregate multiple data from multiple sources into one single window. Within the next couple of years, everything will be ' Web 2.0-based ' : every single information on the Web will be available as a RSS feed. So will be the enterprise' s data : all RSS. Therefore, it's pretty easy to figure out how people will manage the information flow : by themselves - or with the help of small consulting firms (by the way : Web 2.0 could sign off the end of the Big IT firms).
To learn a bit more on Pipes, you may read the very interesting article by Tim O'Reilly " Pipes and Filters for the Internet " here, and Robin Good' s post here.
ps : I bet Apple has brought Yahoo! on board of the iPhone with some leapfrogging ideas based on Pipes in mind.
