It looks ok. I can understand they are trying to jump on the bandwagon with the whole "one page" theme. I think they could have made it look a bit less cluttered though.
I don't like the "tooltip" look of the submenus. The "sign in" popup should be permanently embedded in one of the sections I think.
If they'd given it a bit more functionality right off the bat, less hovering and less reading, I'd probably like it more.
If I were a first time visitor looking for a domain name, I'd probably think I've arrived at the wrong place.
