Ask HN: Academics – What would your ideal publishing platform look like?

I'm an academic in the life sciences and want desperately to move away from all the options we are stuck with. I like arvix.org but it lacks several features that I'd like to see:

1. Allow upload of many more file types (including video, audio, and images). Not all academic content is PDFs and HTML5 exists.

2. I want people to review/comment on my work. Post-publication review is fine by me.

3. Some kind of quality metric (e.g., page views, voting) so people would be incentivized to post their work.

Thoughts?
