question List at multiple marketplaces?

Many here hold the opinion that the best strategy is to acquire quality names and wait for inbound from an end user. If that is your strategy, is there much upside to listing your domain(s) at multiple marketplaces? Perhaps there's the chance that your domain will come up in someone's keyword search, but isn't the keyword search just a way to find second-rate names like "TheGreatName.com" when "GreatName.com" is already taken, or too expensive? Won't serious buyers just type in GreatName.com and proceed from the lander?

If you're selling GreatName.com, do you list at multiple marketplaces?
