feedster.com and similar RSS directories do effectively allow you to create a spiderable profile of your favorite feeds - I've noticed a good amount of traffic from my added feed profile at the feedster.com site in particular.
Feedster is a rapidly growing Internet search engine and advertising network that provides timely and meaningful information to consumers and large Internet sites in need of targeted media. Feedster provides a fresh index across over 13 million feeds several times per hour, adding millions of new documents daily. Feedster benefits from the ways that blogging is changing the Internet’s basic building blocks – from unstructured web pages to structured documents.
