Google Using Toolbar Data for Discovery

This has been happening for a long, long time, but Google does use more than just inbound links to discover websites or web pages. The other day I was looking through one of my website’s “recent visitors” logs, and lo-and-behold, I noted a Googlebot hit on a page… a page that was, first of all, dynamic (somefile.htm?do=something), and second of all — not referenced anywhere online.
