I suspect a "This site only works with chrome!" message only applies to older versions of Internet Explorer.
Crying wolf is so boring these days.
edit: Also i find it hilarious that you think Google would risk rejecting all users who aren't using Chrome. Talk about a great way to give your Search competition a legitimate case.
edit2: The downvoting is cute, and i hope it's because of my tone and not me calling out lies. "Anything but Chrome!" he says - absurd. By all means, downvote my tone, but i should hope outright lying gets similar treatment.
