I think the fuss around this whole subject is looking at growing and refining my work though the comments and rankings I get. Even though there does seem to be other ways around here to get that accomplished, I think it is a natural response to expect to be able to have that happen with feedback in the form of comments and voting. I could have a piece viewed 200 times and get 1 or no comments and or rankings. When that happens, my first thought is "what did the 199 other people think?" So, I think the Hot20 would be a good indicator for that type of feedback, as long as it was clear how everyone could participate in it completely.
