I've heard rumors that all d-names are good...Well, if you provide adult content then any domain name is good, for no one really cares of domain names while searching for porn , otherwise - try find some words that look, sound and may be typed fast and in one way only. And, of course, they'd better be relevant to your business.

I would like to add resale or commercial potential to the list. You want a domain that you can sell off later for a higher price as well.
