For people unfamiliar with Web Development at Berkeley, but familiar with Manifold: What is the Web Development at Berkeley big-little competition?

The WDB big-little competition is a game show-style competition between pairs of people ("bigs" and "littles") who are members of the club Web Development at Berkeley, at UC Berkeley. The gist of it is: every week, for 8 weeks, there are a few challenges that are worth points. Challenges can be easy (get food with your big/little) or very difficult (reach 10,000 ft of elevation with your big/little). The number of points that the challenge is worth scales with the difficulty. Whichever pair gets the most points by the end of the competition will be the winner. There will also be likely two "tournaments," which allow for teams to earn points by placing well in those.

The leaderboard will be updated often once the competition starts

For WDB members and others familiar with the competition, but not familiar with Manifold:

This is where you can use fake money to bet on who you think is going to win. If you buy "Yes" on a certain pair, that is effectively a bet on them winning the competition; if you buy "No," that is a bet on them not winning. Every bet will move the probability a little bit depending on how much you spend on that bet. So, if you think that someone who is currently listed at 10% actually has a 20% chance of winning, you can buy "Yes" on them and earn fake money at the end of the competition if you're right.
