Ah, sorry, my bad.
When a lot of people see UNU for the first time, the first thing they think of is a Ouija board. Basically you enter a thing that looks like a chat room, and there's a "puck" in the middle. When you move your mouse near the puck, it turns into a magnet and starts to pull it. The closer your magnet is to the puck, the stronger it pulls it.
So what will happen tomorrow is that I'll present each matchup, and the two teams will be listed under "poles" and you and about 45-50 other people will work together to drag the puck to an answer.
The idea behind it is something called "swarm intelligence". A lot of people have heard of a concept called "Wisdom of the Crowds", but that's basically crowd-sourcing answers. Which does work, by the way. But what UNU does is create a real-time platform where you see how everyone else is thinking, and people have to make compromises and be willing to settle for their second favorite choice sometimes so an answer is arrived at.
I probably made that sound too complicated. UNU is really cool. The actual process is awesomely simple. The main thing: be there tomorrow whenever the time says in the HIT, and at the end of the time...45 minutes, 50 minutes or so, I'll give the confirmation code that you put in to complete the HIT.
