ProofWiki: a Wikipedia-like system for mathematical results

ProofWiki is a wiki for theorems and proofs. The idea is to gather known results in an organized way, so that it can serve as a repository of complete proofs. It is still beginning, but I like the concept a lot: it could grow as Wikipedia and evolve to be a wonderful reference of mathematical knowledge.
