Mr. Market is a Brilliant Editor

Of the many ways to measure the quality of a publication, one that is often overlooked are the workings of the marketplace itself. Purchases for published material is made in large part on the basis of the quality of that material, making the marketplace something of an editor of genius. This mechanism incorporates all other metrics, from impact factor to altmetrics. Unfortunately, the marketplace is not free to exercise its judgment when many participants seek dominant and even monopolistic control.
