We know that some people put no store in rankings of literary magazines, and yet the lists persist. I've just found a new entry into the fray, and this one is more about raw data than subjective rankings, and I whole-heartedly approve of that methodology. Let the user of the information decide what to do with the data, but thanks to the data gatherer for making it possible.
In this case, The Rankings gives us a list of the best-known anthologies such as Best American Short Stories and Best of the Web and lists the number of times a particular magazine appears. The author, Marc Watkins, does NOT do the same for the Pushcart Prize Anthology because, as he acknowledges graciously, I've already done that here. Very useful information.
