Method and Caveats:
(1.) Only magazines are included (online or in print), not anthologies or standalones.
(2.) I gave each magazine one point for each story nominated for a Hugo, Nebula, Eugie, or World Fantasy Award in the past ten years; one point for each story appearance in any of the Dozois, Horton, Strahan, Clarke, or Adams "Year's Best" anthologies; and half a point for each story appearing in the short story or novelette category of the annual Locus Recommended list.
(3.) I am not attempting to include the horror / dark fantasy genre, except as it appears incidentally on the list.
(4.) Prose only, not poetry.
(5.) I'm not attempting to correct for frequency of publication or length of table of contents.
(6.) I'm also not correcting for a magazine's only having published during part of the ten-year period. Reputations of defunct magazines slowly fade, and sometimes they are restarted. Reputations of new magazines take time to build.
(7.) Lists of this sort do tend to reinforce the prestige hierarchy. I have mixed feelings about that. But since the prestige hierarchy is socially real, I think it's in people's best interest -- especially the best interest of outsiders and newcomers -- if it is common knowledge.
(8.) I take the list down to 1.5 points.
(9.) I welcome corrections.

Comments:
(1.) The New Yorker, Tin House, McSweeney's, Conjunctions, Harper's, Beloit Fiction Journal, and Boston Review are literary magazines that occasionally publish science fiction or fantasy. Cosmos, Slate, Buzzfeed, and MIT Technology Review are popular magazines that have published a little bit of science fiction on the side. e-flux is a wide-ranging arts journal. The remaining magazines focus on the F/SF genre.
(2.) It's also interesting to consider a three-year window. Here are those results, down to six points:
1. Clarkesworld (74)2. Tor.com (69.5)3. Asimov's (65)4. Lightspeed (56.5)5. Uncanny (41.5)6. F&SF (39)7. Beneath Ceaseless Skies (23)8. Analog (20)9. Strange Horizons (14)10. Nightmare (12.5)11. Interzone (9.5)12. Apex (6.5)(3.) Left out of these numbers are some terrific podcast venues such as the Escape Artists' podcasts (Escape Pod, Podcastle, Pseudopod, and Cast of Wonders), Drabblecast, and StarShipSofa. None of these qualify for my list by existing criteria, but podcasts are also important venues.
(4.) Check out Nelson Kingfisher's recent analysis of acceptance rates and response times for most of the magazines above.
(5.) Other lists: The SFWA qualifying markets list is a list of "pro" science fiction and fantasy venues based on pay rates and track records of strong circulation. Ralan.com is a regularly updated list of markets, divided into categories based on pay rate.
