Side note (as a scientist who uses the site): there are lots of different ways to share an arXiv.org link, but in almost every case the best option is this: http://arxiv.org/abs/1403.1211 http://arxiv.org/abs/1403.1211 That links to an abstract page for the same paper you linked to rather than the full PDF, and it's a lot shorter to type (and less specific about format). This form often avoids accidentally linking to an outdated version of the file, too.
