A concept that applies the basic premise of the Hot Or Not rating system, Twit Or Fit is there to make following the right Twitterer an easier task, or at least to try and make it a more entertaining one. Working on a very simple model of rating profile pics on whether they are good looking or, err, not, Hot or Not raced to success in the nineties with such a simple and fun model and has since grown into a very successful 'social entertainment' site. TwitofFit.com works in the same way and provides the opportunity to find new people to follow on Twitter, the fast-growing micro-blogging site.
