I was curious so I did a quick search and these are the ones I found. A lot of poll threads seem bugged and don't display the results. I believe the old ones were lost with the site overhaul. So far, Sherdog has been surprisingly accurate, only being wrong when it's a close split decision where follow up polls show the majority believing that the loser should have won.
