Pipes: Rewire the web

Pipes: Rewire the web: "Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web.

Like Unix pipes, simple commands can be combined together to create output that meets your needs:

combine many feeds into one, then sort, filter and translate it.
geocode your favorite feeds and browse the items on an interactive map.
power widgets/badges on your web site.
grab the output of any Pipes as RSS, JSON, KML, and other formats."
