Arxiv detracts from, does not add, to credibility.  it&#x27;s an open preprint platform after all.  This is like saying &quot;No way such an important project would be anywhere other than github.&quot;  That&#x27;s not much of an argument.<p>As for flaws, it&#x27;s four pages.  They can be written up in an afternoon, if the paper makes sense to its intended audience.  Of course, that&#x27;s not exactly HN.<p>EDIT: Very interesting replies.  I&#x27;ll leave this up, though apparently quite wrong.
