I'm pretty big domain collector, and to be honest, I see no compelling reason to use this service. Something like Freshdrop.net, which allows sorting by numerous data types, searching, and the ability to get the jump on newly expired domains is much more useful.

Of the 10 most popular domains, only 1 (campdeal.com) is moderately attractive. I browsed through a bunch of the categories and most of them were terrible. There is also no ability to search a keyword and have relevant names appear.

I would be very interested in a service like this, but you will need much more functionality to compete. I think you may have opened up for review before the product was ready.
