I think that many of you will find interesting such a question: which papers download best. Often researchers download articles without going into details of their contents, and start making a close study of the papers only after downloading them. From my experience, I can say that all else being equal, the articles that download best are the ones with mathematical models or the ones with catchy titles. What do you think about this? Has any one you happened to determine any relation between your own citation index and the number of downloads of their articles?
