Arxiv is a good blueprint for what we should build on. Terry Tao gave a recent talk about how "canonicalization" is the key bottleneck. The limitation of Arxiv is that is non-canonical, non-peer reviewed. However, there is no reason that journals should have a monopoly on peer review (it should be noted that peer reviewers aren't even directly compensated for it, granted it is supposedly "priced in" to academic salaries.)
