Ask HN: What is your critique of Scitr.com?

[Scitr]

If you find an interesting research article, you can paste the DOI into Scitr.com and leave a comment. Then others can find the most interesting scientific news, but instead of a middleman news site, it links directly to the research article.

Cool but your biggest challenge will be adoption. If you expect users to be repeat ones, I would consider some sort of browser extension or work with sites to integrate your button on their site much like how twitter/facebook share buttons are pervasive these days.
