Following the redesign of the Physical Review C website, they seem to have created a new feature for the front page called "Kaleidoscope". Phil, my PhD student pointed out to me last night that our most recent paper features there on the front page (though as of right now it's no longer the newest one, so is not quite at the top of the page any more).
What great aspect of our work got us on the front page? To quote the PRC website: "Please note that kaleidoscope selections are based on aesthetics and not necessarily the scientific merit of the paper" Oh well! At least there is a new route to get your work highlighted on the front page - make sure you include at least one really nice picture in your paper.
