Show HN: Grab a Random ArXiv Paper

I needed a way to grab a random paper from arXiv, so I built one and wanted to share it with you.

It 1) picks a random topic (of all the cs., econ., math.* etc. topics) 2) finds the maximum amount of papers in that topic, and 3) queries for a random paper in that topic.

Note that this skews the distribution heavily in favor of topics that are less common, but it should get the job done. Suggestions for improvements are welcome.
