I decided to make a project recently to find unregistered domain names, the site is pay-free/ad-free, just going back to my roots of making a project for the fun of it. The reason for making the project is explained here:

http://blog.geek.name/2007/01/geekname-project-finding-unregistered.html

or just http://geek.name for the project itself

...just trying to spread the word to people that are like-minded to me. i don't think of this as spamming as its completely non-profit/fun.
