Domain Superstar is a joint effort from both Joel Obman and John G. and has really just made its debut.
The catch for me is that this is a well picked over list by domainers and the chance of finding a great name is relatively low unless you are in a niche that is not exploited yet. I do like the idea though of taking the results of one search and seeding it for a new search to find more peripheral domain names. There are possibilities here for those that think a little outside the box.
Almost every domainer has a favorite way of catching dropping domains but the tools on this website give you another alternative. The tools certainly seems to work very nicely and quickly. A few searches will show you the rubbish people register as domains but sifting through this can yield some valuable domains from time to time.
