The model of scientific and scholarly publishing is, arguably, undergoing a fundamental change.  Once upon a time, the business model was simple:  publish high quality articles and convince as many people as possible to subscribe to the journals in which they appear and raise the prices as high as the market will bear.  We all know pretty well how that works.

But now an alternate model appears:  charge people to publish their articles and give them away for free.  The fundamental change that implies is that revenue enhancement will still come from charging whatever the market will bear, but now the search is not for more subscribers but for more authors.  Of course peer review intrudes into this model, but if you could, for example, double the number of articles passing peer review for a journal you publish, you could double your gross revenue.  That was mostly not the case before except where the publisher had room to increase the subscription price proportionately.  There's a slippery slope here.  Predatory journals have already gone over the edge on that slope and are in a smoldering heap at the bottom of the hill, but the footing can get dicey for the best of them.  Hence this story:
