With Google tweaking its algorithm to help eliminate content farms, I wonder if many of those premium parked domains will start to go up for sale and come down in price. The squatters make a lot of money by parking domains with link farms and ads and get a lot of search traffic from natural Google results historically which they then make money on PPC advertising. Well if that traffic goes way down with Google’s recent tweaks, some of those domains may end up back on the market with lower premiums. Keep an eye on Demand Media over the next few months
