It's good that your switching on your analytical mind DBS The previous poster has pretty much summed up why the two "words" you've quoted are Poles apart. (literally and value)
I think most domainers would agree that $90K for the 'defiance' domain is a nice sale for the seller. domains are about maximising those opportunities to capture a sale of that magnitude - that wont happen with words that don't have the right connotations.
incidently I actually have the dictionary plural "connotations.couk" probably registered after a good few glasses of scotch and an extremly healthy bank balance at the time. I'd put it in the same ballpark as your "concede" domain next to zero. So looks like we are both hoping for a 'board game manufacturer" on these ones
