Looking for a domain name for your niche or blog?

So I was dinking around with the adwords and Google apis and I created this l33t domain name generator. located here http://dev.shoemoney.com/public-tools/domainfinder/ Basically you give it a keyword for a niche that you are thinking about doing and it will query AdWords api (which I have unlimited calls atm) and the Google api to find popular searched for and high paying keyword phrases then it inserts hyphens and checks to see if the domain is registered. Its pretty elite cause it will find the best possible domain for the keyword you give it. This should be a nice tool for those probloggers who are trying to make a living from niche blogging. I am not sure how long I will leave it open to the public. In beta it was getting hammered pretty good and Im pretty sure Matt Cutts would dissaprove =P. I know he does not like the spammy-hyphen-domains.com But honestly is this a bad thing? Curious to hear some of your comments/thoughts.... Here is a example for those who have not tried it- For the keyword of roger it gave me roger-rabbit.com For the keyword of fish it gave me animal-fish-general-pet.com For the keyword of fluff it gave me marshmallow-fluff.com For the keyword of google it gave me google-image.com (wow thats a pretty good one lol) For the keyword of nextel it gave me new-nextel-phone.com and so on... Keep in mind these are not only suggested domains but they are domains that are available to be registerd. I confirmed these results with the Yahoo Search Marketing (formally overture) db and they were all the top overture searched for phrases so I think this might be pretty useful (or dangerous) to the right person.
