Searching Virtual Self

I did the on line activity...searching myself actually before I read the articles on search engines and how they work. The first engine I searched did not have me anywhere I could find, even though it is one of the sites suggested. I thought that I was "virtually" no one. :) Then, as I searched myself on the other suggested engines, I found myself. That is when I realized there must be different methods of tracking and prioritizing information. I found the differences between the engines and the "borrowing" between the engines very interesting.
