Pipes lets you remix feeds and create new data mashups in a visual programming environment

Yahoo just blew me away with their new Pipes service. Innovation is not dead at the purple Y! I've just read a little on it and touched the service, but this looks better than sliced bread. I need to check it out more after I get some sleep.

Don't take my word for it, a few people describe and explain it well: Yahoo's Jeremey Zowodny, Tim O'Reilly, and Google's Matt Cutts. Feel the love.
