I found this website while surfing the Ittutor.net forum, the Linux Distribution Chooser tries to determine what kind of GNU/Linux distro is best suited for you through a series of easy to answer questions. Suprisingly, the results are fairly accurate, my personal result was Ubuntu, Kubuntu, Mandriva, Mepis and Debian.
IMHO, based on testimonials from ittutor forum, this website can help users to determine the right GNU/Linux distribution for them.
