You can now measure your web populatity, sort of, with egosurf. Enter a search term and a domain and you get back a handy metered result based on Google, Yahoo and other's ranking and positioning. I find the results somewhat suspect, Bill Gates and microsoft.com does only slightly better than me (6484) on Google. My EgoSurf rank for is 5964. But it's fun. At almost 6,000 I'm not doing too bad!
My EgoSurf Yahoo! rank however, is through the roof!
