So, just for fun, as an example since Bills.com just sold for almost one million dollars, what would Bills.cc be worth?
IMO and a bit for fun also, a generic word .com is around 1,000 to 2,000 x higher valuated than the .cc (or other 'similar' extensions) , so that makes Bills.cc worth around $ 500 to 1,000. In the future this 1,000 to 2,000 x will be more like 100 or 200 x. So the future value of Bills.cc would be $ 5,000 to 10,000 (if the .com version stays the same value). BTW future is in 5 to 10 years from now.
My own example: loans.com was sold for 3 million (okay, I know, it was in the bubble, but still..) and I bought loans.cc for 600,-, so here the .com is 5,000 x more expensive and that makes absolutely no sense to me. Imagine you have 3 million, but decide to buy the .cc and spend (part of) the difference on extra marketing.

Of course this is all IMO and really a rough estimate, just wanted to get some figures out, John.
