Some random thoughts... I don't want the Hot20 to simply go away because I like the idea of having a gallery showcase (after all the site isn't just about the artists, it's about viewers too). It's a good way to explore a gallery one doesn't visit often, provided it isn't the same people being all over it all the time. That's why I'm in favor of having at most 2 images from an artist at any given time. I also liked the idea of the images appearing in random order without the number of votes. That makes it less of a contest. I'm not sure about restricting the people who can vote in a gallery, because I don't know how much of a problem votes from non-posters cause and it doesn't address people voting for their friends because their friends voted for them. I'd guess the latter happens more often than the former.
