we have toyed a lot with the idea of stats and rankings on sito, believe me. for quite literally years. we have some ideas, and are really trying to find a way to balance things so it doesnt become a "competition" and yet things are useful, not to mention fair and easy to understand.
needless to say, we havent actually done much on this front because we keep kinda fussing over details. whatever we would do, it would likely be something more like mixing in most-viewed with least-viewed with some random ones. and presenting it as just an array of images. or something. (you can see why we have gotten nowhere with this... haha)
thanks for the suggestion tho; it adds fuel to the fire.
