I view Rifftrax on Twitch alot. It would be cool if you guys implemented a !vote command for the next video to be played. I recommend checking out Yogscast on Twitch and at night EST time they do a Twitch Plays segment with videos were viewers vote on the next one to play. I'm not sure how you can implement it, but it would be cool if done (you'd prob have to message Yogscast for whatever mod/command functionality they use on their stream. See attached for a screenshot from Yogscast Twitch channel.
