Yahoo! Pipes – News nuggets served piping hot
A news feed aggregator recently released by Yahoo is not just an aggregator. It allows users to configure your various news feeds, consolidate them, filter them by specific keywords, cull out redundant news items and present a single feed. Not much? They provide basic building blocks to perform all these operations and allow users to program by plug in the blocks very much like Lego in a graphical manner!
