I assume the way you will be earning revenue will be adsense. However when you click links from your Top Lists tnone of those pages have Adsense on them. You should have adsense on every page to maximize the possibility of making $. Good luck Dan

your idea is going to go far i can already see it may be you should sell the idea to other established sites or start one on your own and do a merger to this script!
Didn't really get it at first. There are a fair few sites around that deal with similar themes. Nothing special on your site to drive me to bookmark
