Ego Search is a pipe for finding out how popular you are on the web, based on search results from popular search engines.
The popularity chart is drawn based on the number of search results that point to your blog or domain name for your name.
And if your name is say 'xyz', a 100 point popularity rating on the graph says that you are the most populous 'xyz' that the search engine knows.
