Suppose you have a draft paper that you think is pretty good, and people tell you that you should submit it to a top journal. How do you work out where to send it to?
Coming up with a shortlist isn't very hard. If you look for generalist journals, it probably begins:
How do you begin deciding amongst such a list, however? I know that you can look up eigenfactors and page counts, and you should also look for relevant editors and perhaps hope for fast turn around times. Depending on your politics, you might also ask how evil the journal's publisher is.
But for most people thinking about submitting to a good journal, these aren't really the right metrics. What I'd love to hear is something like "A tends to take this sort of articles, while B prefers X, Y and Z." This sort of information is surprisingly hard to find on the internet.
