That's interesting, when I was preparing to launch I saw an app with the same concept where startups "buy" their country on a world map. Some of the countries like Norway were "premium countries" so they cost extra for placement. I doubt anyone will think of that site in a couple of weeks. I thought it was kind of novel but I've now seen a couple more that are just blatant cash grabs like that.
