There's a new Wii Channel out, called the "Everybody Votes Channel". However, to acquire this new channel you must upgrade your Wii's firmware and then download the "Everybody Votes Channel" in the WiiWare section of the Wii Shop Channel, for free.
The everybody votes channel allows 6 of your Miis to vote and make opinions on just about anything. These questions can be either state-wide, country-wide, or worldwide!
And you can also submit questions to Nintendo that you think would make good poll questions for the future of the channel.
I will be making a video demo of this channel in due time, as I did with the News Channel.
