I&#x27;ll go out on a limb and answer that on Dan&#x27;s behalf:  Yes, please post these links in the comments.  They are a benefit the community.  Dan&#x27;s needs to walk a fine line between having working links and not being sued by evil companies.  This is what he is referring to in some of his comments when he mentions &#x27;lines that should not be crossed&#x27;.  He can&#x27;t (read &#x27;would be wise not to&#x27;) offer you blanket permission in advance to post such links. The link may even be removed in the unlikely (?) event that HN receives a threatening letter from Elsevier, and at that point, a policy may be loudly proclaimed.  But until you are explicitly told not to, please keep posting the links that let people read the publicly funded research.
