This is an experiment to see whether I can quickly find relevant web sites based on people's tags/bookmarks on del.icio.us, using a home-brewed association engine. It answers the question "people who tagged this site also tagged what other sites". I am using it mostly to find blogs that are similar to the ones I read, and to find new popular web sites that are in my area.
For example, if you like Neatorama, here is a list of other sites you might like. You can enter any URL and find a list of associated sites. You can also add this application to your browser toolbar. Link -via Evil Mad Scientist Laboratories
