I wrote about Yahoo Pipes previously and finally got around to playing with it. I ended up creating a very simple "pipe" which combines the RSS feeds from GigaOm, TechCrunch, VentureBeat and Mashable. I call it GigaCrunchBeat, Mashable is implied.
I import this feed into one module on my start page instead of four, works quite well. This doesn't even scratch the surface of the power of Yahoo Pipes. With Pipes, you have an assortment of functions which allow you to process, analyze, combine feeds in various ways. Browse through the Pipes directory to find other user created pipes.
