Yes. But given that, you can look at the distribution of stuff around us and the radiation reaching us to conclude whether we are in any special place. How you would conclude from the CMB to be at the center of anything though... Maybe Krauss responds, he is usually not keen on feeding Creationists with talking points. But he likes to make a bit theatrical statements to get your attention.
Well, every map I've seen of the CMB looks like a fairly random spatter painting. If there's unusually high or low density somewhere, I'm not seeing it.
