What I meant was a link
like this, directly to the ADS reference, which has more descriptive links than the results query page. If one is to link to arXiv instead, definitely link to the abstract page, since one can get the paper in the preferred format, and trace citebase links, etc.
And your own admission to not being aware of either Bad Astronomy nor Universe Today brings up another point: people don't follow links (those two sites are linked from the banner at the top of the page). Even if you include a FAQ with links to more information, I'm not sure how many people would read them.
