The Supplemental Index is enough to drive any webmaster nuts, even one who was partially sane when she started. And now Google’s own webmasters needs to figure their way out of Supplemental Hell. A view from the Google site command shows Google having a huge number of supplementals. This belies much of what has been said by Google about the index.

You’ll notice that Google even has a number of “session ids” in their URIs. I wonder if the webmaster over there will be in trouble today if the search rankings plummet?
