(Some of the suggestions may go better together.)

1: Recursive voting.

If there’s a huge bum tie maybe taking the top tiers and allowing everyone to vote again would resolve some of the issues had. In the same, it gives people a second chance if the poster they voted for got DairyQueen’d. It should also give up if the results are the same three consecutive times. (Still respects two players’ ability to tie.)

2: Time reduction.

Perhaps there should be a system in place to take a tiny poll to reduce the time on the current entry by a fraction. Especially useful when everyone who’s at the computer already made a submission.
(Maybe limit access to people who have made a submission? Maybe each person who makes a submission and votes for a speed up automatically nixes a bit of time off? —That might be bad, causing a bunch of **** submissions all nudging for a different image, see suggestion 5.)

3: Vote highlighting.

It’d be nice if on the results page the submission that I voted for had a background of yellow because I have a very short attention span.

4: DQ count.

Even if votes end up completely DairyTrained, it’d be nice if not humorous to know how many people voted for a DQ’d submission.

5: Skip image.

Though this could somewhat be partially done by the time fractions, I thought it’d be worth something to mention this on it’s own.

But wait, X will Y!

C: The skipping time will speed up the entire process which means more scoops being distributed meaning a possibly huge upset in the Domination economy!
