If you have the $$$ to set up a few of these you could make some serious $$$ if you can get a high level suffix like sex or loans. Imagine leasing or auctioning off domain names like hot.sex or refinance.loans. At least in the beginning before all of the hype dies down this is going to create a virtual real estate frenzy. I also think that in the long run it's got the potential to create an absolute clusterfuck. Was the site I wanted to go to "levelnight.clubs" or "Level.nightclubs"
