The arxiv should itself embed a review and commenting system, possibly even blogging. Publishers are archaic, scientific social media should be arxiv's future.

The risk is that publishers might then start opposing the publication of manuscripts that have been shared as preprints on arXiv, if they start perceiving it as a competitor and not a supplement to their "service". But I concur, arXiv with social media features would be nice.

I like this idea.

But it should be a separate entity for robustness's sake.

Let's make it! We'll even hold weekly live video/audio discussions on each paper for it's lifetime.

Let the errant and emerging thoughts of researchers accompany the original research so we can better iterate and grow. In the open.
