I was curious to see if there were any top level domain names unregistered.. sooo I downloaded a dictionary, wrote a small macro/ script that pulled 500 terms at a time and checked them on godaddy. If they were available it then stripped the .com and checked them in adwords for exact word searches. If the term had more than 1k searches performed it saved it.
My results were that 1/5th of all terms in the dictionary I downloaded weren't registered, and out of that only 7 met my requirements.
I consider it a fail. way too many adj. Next time ill check just nouns. Nouns make money.
