Completely and utterly deserved. Arxiv, like Wikipedia and arguably sci-hub, is an absolute boon to humanity. What I find interesting is that its endorsement system does largely work at making it very easy to submit papers whilst reducing the amount of spam. Sure, there are some papers that are not completely brilliant -- or indeed, actually any good at all -- but they have the same "right" to be read as their huge CERN brethren. In some fields of physics, paid journal publishing is really a niche in comparison to stuff on the ArXiv. In others, and other areas of science, not quite so much yet. I also very much like the fact that it is open, mostly LaTeX based (machine-readable maths!) and free.
