An added feature I would like to see implemented would be run-off voting.
Personally, I like 2 or 3 sets, and it would be great to be able to cast a
weighted vote, such as your top 5. This would make the final vote much more
fair for both users and artists.
Algorithms for run-off voting are not difficult, and you should be able to
find plenty of examples from google.
Thoughts, anyone?
