Superfeedr is a website that can pull real-time data from Flickr and Twitter, then feed it into the standard ATOM format so that you can “parse one sort of feed no matter where it came from.” The company makes money by charging web developers for tracking over 1,000 feeds. Its a very niche service and I am not aware off-hand of anyone I know that would use this service.

Mark Cuban and Betaworks have recently invested in the company. Andrew Anker and David Recordon has joined the advisory board as well.
