RSS Mixer

RSS Mixer allows users to mix multiple web feeds into one new RSS feed.

RSS Mixer is a free service that allows visitors to efficiently mix multiple Web feeds into one. The mixed feed is then viewable as a new RSS feed, Web page, and mobile formatted page. All mixes and feeds in RSS Mixer are also available in 5 widget formats: Apple Dashboard Widget, Yahoo! Desktop Widget, Google Gadget, Vista Desktop Widget, and as an embeddable Web widget. There's also a Media Player Web widget that plays mixed audio and video podcasts. RSS Mixer is also a searchable directory containing thousands of mixes, tens of thousands of feeds, and millions of posts. RSS Mixer has two primary backend components - a fetcher (a proactive caching HTTP proxy), and a feed parser. Both can scale over clusters of computers.
