I'm trying to find a plugin similar to the star ratings for posts, but a little more specific in its purpose. I try and write my blog content specifically for certain frequent visitors and I want them to have a way of letting me know which types of posts they want to see more of, and vice versa. If there isn't anything like that, the star ratings will have to do, but I'm hoping there's a similar plugin where it simply allows readers to click "More of this!" and "Less of this!" etc.
