See also, manifold, for a play-money predictions site based more around market mechanisms:

https://manifold.markets

Both sites come out of the same sort of rationalist bay-area circles, manifold even changed their site to look like metaculus on April Fools.

Yeah! I think of Metaculus vs Manifold a bit like NYT vs Twitter -- or to borrow another analogy, lawful good vs chaotic evil. But we're both great places to think about the future in a bit more structured way than pure punditry!
