Those sites only seem to value domains on the basis of things like traffic and pagerank. I own a .com domain that is a three letter, cool sounding English word (I bought it 15 years ago). Those sites calculate the value of my domain at about $1000. Since I've already turned down an offer of $60k I'm certainly going to ignore anyone offering what is hardly more than pocket change.
