There is growing consensus in scholarly communication circles that academic publishing needs to move "beyond the PDF" (see the manifesto of Force 11). PDFs are a great portable format for printing, but they are not the best format to share, discuss, and read on the web. Every article on arXiv is a PDF (built from LaTeX). As such, it is static, 2-dimensional and non-actionable. It is not a stretch to say that a paper in PDF is merely a digital photograph of a piece of paper. We can, and are doing, better than that. Authorea's repository is a collection of Open Access and Open Science (i.e. data driven) web native papers.
