The service will be put in read-only mode until we will discontinue Yahoo Pipes on September 30th 2015. You can find more details here.
This sample shows you how to build a community-powered feed built with Del.icio.us, Flickr and Google Blog Search. It is an example for my Working with Yahoo Pipes series, see http://martinkelley.com/tag/pipes
