Published feeds are modified in several ways, including automatic links to Digg and del.icio.us, and "splicing" information from multiple feeds.[5] FeedBurner is a typical Web 2.0 service, providing web service application programming interfaces (APIs) to allow other software to interact with it. As of October 5, 2007, FeedBurner hosted over a million feeds for 584,832 publishers, including 142,534 podcast and videocast feeds.[6]
