"The producers made an effort to create a geographically, racially, and regionally diverse group of bakers..."
I'm going to suggest that this is the problem with this (and so many US reality shows). "Okay, we need somebody black, somebody Hispanic, a gay guy, someone from the south, someone from California..." Why? Do you think people won't watch unless they find "their" group represented? This insistence on a casting formula dilutes everything. It's a baking show - cast the best bakers you can find, not the best who fit your profiling formula.
