Search engines are pretty much what drive the net. They help people find you and your search engine Page Rank, or Web Rank is talked about everywhere. It helps the engines define how popular you are based on how many links you have to your site as well as other factors I don't have time to explain, nor completely understand.
So what happens when a search engine comes out and lets the users actually rank your popularity? Well...right now, Sproose home page offers just that very feature. Just type in a search and the index will come up. Then you can rate the relevance of the sites that come up with a 5 star rating system. 5 being best and 1 being worst. You can even remove the site from the list altogether for your searches.
