I recently stumbled across this number, and then (foolishly, most likely) decided to try to describe it in a blog post

http://frothygirlz.com/2010/01/14/big-numbers-part-2/

Q - Are there any comparisons of Graham's Number, hell, even G1, to other well known "big" numbers, such as googolplex?

I'd just like to have some way, however abstract, to be able to pretend that I have some sort of idea of the magnitude of this number.

Any help and/or tips would be much appreciated.
