I don't know if there's an official name for it. You know... "hot or not", "rate my car", "rate my poo", etc... Do these sites perform well in terms of ad revenue? I have a potential niche I think I could promote well (I'm a fan of user-generated content sites) , but I don't know if "rate it" sites are worth it to begin with. If so, any potential script that's considered 'optimal'? Whats the difficulty of running a site like that? Basically just looking for opinions of anyone that has experience in these kinds of sites. Thanks.
