You wait longer.
If they added a new poll every single day they'd probably be REALLY boring ones by now! :)
But they do add new ones as new ideas and info come to light.
Why don't you quickly suggest, right now in this thread, 20 new poll ideas? They have to be things that aren't already done, and relatively interesting. You don't have to come up with poll answers, just question ideas that they can use! That would help them out a lot with making new polls.
