Off topic - I find it humorous that arXiv list 49 authors and then ends the listed author list with: "et al. (1 additional author not shown)" I know a line has got to be drawn somewhere but in this case, listing the last author (Jason Yosinksi) would have taken less space than the explanation that not all the authors are shown.
