Here are some aspects of the show I think viewers would actually like to vote on:
-How many minutes should Samantha get to ask people who have already danced and been judged inane questions about how they feel about the good/bad comments they just got?
-What musical guests would you like to see on the show?
-If you could bring back a star from a previous season for a second chance, who would you most like to see?
-If DWTS were to pair up the stars with each other for a week, which two stars would you most like to see dance with each other?
-Which of the following non-paso songs to which we are going to make people dance paso least makes you want to do violence to yourself?
-Which of the time fillers that we stick in late in the season are least likely to make you lunge for the fast forward button?
-What color fabric would you like to see draped over Edyta's sparkly bra this week?
-During which week of the show should Maks take off his shirt?
-Over all the seasons of Dancing with the Stars, what was your favorite number?
