Some interesting discussion is happening on the H-PolMeth list over an apparent policy by the editors of the American Journal of Political Science to reject papers for a variety of reasons, most controversially including summarily rejecting any article that advances formal theory without an empirical application of that theory. Without taking sides (I can always hope I might get a pub in the AJPS someday, and the people on the other side of the dispute include at least one good friend of mine), all I can say is that this one could become highly entertaining real quick.
