YouTube's Super Bowl ads page is looking mighty fancy this year. They've created a new voting platform called Supervote. If anything, it's looking a little bit like Reddit with hot or not voting that moves each ad up or down based on user votes.
The page was set up as completely separate from the actual viewing gallery.
What interests me about this is whether or not this might become a permanent fixture on YouTube. There's already a star system for voting on YouTube videos, but having user-chosen list on the front page of YouTube as a replacement to the current listings for popular videos wouldn't surprise me.
