Nobody follows the Billboard charts anymore. In an age of music downloads, the "Top 40" ranking is pretty meaningless. But who cares about that music stuff when you can keep track of the top scholarly articles at  the Social Science Research Network?

In fact, today, readers will be happy to find that Matt McCaffrey's [2] article "What's Love Got to Do with It? Action, Exchange, and Gifts in Economic Theory" [3]is near the top of the charts in two categories. He's number 4 here [4], and number 6 here [5].
