Althouse notes that Room Rater isn't into neutrality.
True, but I suspect he was having a quasi-religious experience.
Besides that, Room Rater doesn't pretend to be neutral.
[On the other hand, I heard National Public Radio the other day and wondered, "Do you people ever listen to your own shows?" It wasn't even close to being objective.]
So Room Rater gets a pass. Part of its appeal comes from snark and unfairness. If the background in the Obama room had been behind George W. Bush, then you can bet the Texan's empty shelf spaces would have been mocked.
We live in mean times.
