@Mr3putt I've heard this theory, too.

I've got one main broad-topic site which took a hit, and a few narrow-niche sites, which all seem to have benefited from this update. None of them have keywords in the domain.

I wonder if what you're seeing isn't so much the keywords in the domain, but the effects on targeted, narrow niche websites?
