My domain name is an Exact Match for a keyword. I just searched through to page 41 in google, and thats where I sit. Not my homepage though, for some reason google wont rank the right pages for anything. Instead it ranks a random post on my site that does not have the KW in my domain name any place.
It really seems like an over-optimization penalty, but my number 1 competition also has a KW match domain name and ranks for everything just fine with less content per page, and less pages overall.
