Just checked it out. They have a nice use of AJAX but it's a bit overboard.. like the fact that there seems to only be one page total.
However much they paid is irrelevant unless they have about 3 times that left for advertising. Nickle and Dime hosting companies are a dime a dozen, and from the looks of it they have super cheap shared hosting and that's it.
While they look like they have been pretty successful, I'd also like to know how much they paid for one.com, since it will be interesting to see how long it will take them to turn a profit on the decision.
