This is one thing we're considering.
We're also adding a bunch of different formats and features like restricted upload periods with no voting.
In addition, we're experimenting with different voting formats. We might leave the ability to choose voting formats for different contests, or allow things like selected judging panels.
We're also working on some mathematical formulas to normalize the 1-10 voting, to reduce the effect of someone just trying to rig the contest. In some way, shape or form, I hope to keep the 1-10, as it allows us to run things like our online slopestyle contests, which might have many people go into a semi or finals round.
Remember the broadband uberopen? Chance to qualify for the US Open.
Under Armour Slopestyle video open? Chance to win like $5k.
Both of those wouldn't work with a thumbs up thumbs down type deal because it wouldn't necessarily rank people for the qualifying rounds properly.
We'll get this dialed. The key is that we have so much participation and passion about the contests - that means we can get more of them with better and better prizes. Few tweaks to the contest system are barely as hard as getting so much interest in them.
Take into account that these things have been around since the winter of 2005, and its only now that the popularity has skyrocketed to such extreme levels.
The internet is weird.
