Like most religious "proofs" the 9 proofs of Googlism are rather carefully selected to give the results they wanted, and rather circular in nature. But that doesn't knock them out of the competition by any means. With over 11,000 religions out there, its hard pick just one as "the one true religion."
I think a better question is "what is the best spiritual path for me?"
And while I find Googlism interesting, I don't find it satisfying.
