I'd like to set up a blog (or forum) where posts could be rated by readers. The idea would be that each post would represent an idea. The idea would be discussed via comments and each reader could rate the value of that idea, say, on a scale from 1 to 5. The average rating would be displayed next to the post.
Anybody have any idea how I could do that? Is there another system I could use to accomplish it?
Thanks very much for any insight anybody can offer.
