People...they're marketing folks. To them, 'googleplex' is what you name an arena after Google buys the naming rights. So, please stop acting surprised that they don't have a clue about the true meaning of the word. BTW...'frooglepoopillion' is my new favorite number.
I find it somewhat interesting that the number is actually spelled 'googol.' In fact, I "googled" it one time to refresh myself on it's meaning and misspelled it. I'm sure at one point we all knew how to spell it but thanks to Google the correct spelling has been forgotten. Now you'll never forget haha.
"Is a frooglepoopillion bigger than a gogolplex? Somehow I doubt it, especially since it seems to hold on a sheet of paper... ;)"
I think that's just his sheet of notes. Or it could be in shorter form; for example, 5.68 * 10^googleplex
