Decentralizing Disqus is trivial. Just go back to each blog has its own local comment system with commenter identities disconnected from all other sites they comment on or even anonymous. There's no reason you need a single global identity and storage backend for all content sources that support commenting. It can even be otherwise identical to Disqus except self hosted.
