thingsthatyoucandowithrss is a wiki that is about exactly that – things that you can do with rss. Some interesting ideas here and if you know of other uses for rss you can just add them to the list and let everyone share your wisdom.

Services like technorati.com, pubsub.com, Feedster.com, Blogdigger and Blogpulse offer something that’s popularly called persistent search delivery. You type in a search term such as your name and or your company name or product name and they will return the newest indexed references to you in a customised RSS feed. These services scan blogs. If you want persistent search delivery from a broader range of sites, Market Sentinel offers a service covering message boards and corporate pages as well as blogs. “
