Why not have a multi tier system in which articles are marked with their validity? The internet will probably replace "published sources" becoming the place where "original research" is done. If wikipedia hold on to this outdated standard of correctness it will fall into oblivion with the rest of paper media. Wikipedia could have become the next publishing platform, with cryptographically signed articles/papers, and cryptographically signed peer review. I would rather trust a wikipedia article that has been signed by a thousand watchful eyes, than a scientific article that has been looked at by a couple researchers and publishers.
