I'm pretty sure not that many people know what Brainage is or get the gameboy captain N reference so that's why no one cared about the Stroopid Test.
Yeah, but I targeted it to game sites, places that normally would "report" on that sort of thing. It's not like a sent a link to collegehumor or anything.
As for people not knowing what Brain Age is, must I say this again? It has already sold through hundreds of thousands of copies. In Japan (I don't expect the Japanese to watch or get the cartoon) Brain Age 1 and 2 have sold well over 5 million copies. As for the Captain N reference, who the heck cares? It's two seconds, it doesn't make or break the whole thing.
