For the record, if you're using DW's crossposter, then polls will simply link back to the poll on DW, rather than use a separate poll on each service :)

Also, maybe you already know this, but just in case you don't: if you just want to see the answers on a poll, you can just hit the submit button without ticking anything. That'll then count you as having "answered", so you'll see the responses every time, but since you didn't select anything, you won't affect the graphs.
