What's the most valuable domain available? Is there one that trumps all the rest in terms of value? I know business.com and stuff sold for a lot. But is there one that's sold for more? I wonder how much google.com is worth?

I think rock.com would sell for a lot. I think genre names like that would generally sell for a lot of money. It's one of a kind-well all domain names are-catchy and, I think, lucrative. You have the rockmag.com and other sites with rock.

I think that the spelling of google was the second choice for that site. I heard that the first choice of the spelling was "googol" which means a number equal to 1 followed by a hundred zeros.
