I can think of a few things that this would indicate (probably my own wild inconsistency--in quality or in content, I shall not presume to judge *g*). But mostly it does tell me that a scattershot approach to marketing is more or less a good thing, because it gets as many stories under as many noses as possible, increasing the chances that the right story will find the right desk on the right day.
Which reminds me, enough sulking. I have five short stories here ready to go back out. They go out tomorrow. Assuming I can find markets for all of them.
Always the rub.
