A few years ago a nice paper surveyed the differences in quality between papers submitted to arXiv and those submitted to arXiv's rough cousin, viXra. However, that paper was about generic contributions to natural sciences, whereas this post on Quora is somewhat focussing on physics. Whence my question: what's the shape of maths on viXra? Should one ever bother to take a glance there, too? (I've just checked the contributions in analysis and I must admit I was a bit scared.) Are you aware of any mathematical article later quoted by, say, more than ten different peers and originally published on viXra?
