> Their reported beta-testers usage is 30 / day. At their current expense level, that would be $116.25 / mo.

30 searches/day comes to around $11/mo. We expect the quantity of usage will drop with time because

a) we make a better product that helps you find stuff more quickly (so quality of usage goes up)

b) lot of users are still searching more then normal because of novelty of product, testing etc.

Of course we could be wrong :)
