Seeing a website as an RSS feed

I've been thinking about rebuilding the architecture and some of the design of this site to adopt to tags and XML. I'm starting to see the site as a large feed reader for my own content. The intruiging part is that if I rebuild this site to work directly off of my RSS feed then it will work on anyone's feed. The site becomes simply a database app for a standard type of data. I've always thought as websites as the result of database programs, but the more I grok RSS as a delivery and storage mechanism the more opportunities I see for working with it as the core architectural structure rather than an export or import protocol. Hopefully these ideas will become more clear as I build the next iteration of this site.
