Not exactly the answer you requested, but I used to read all three of those when I was younger (well I only bought Interzone on occasion from a store that had imports) and have been feeling the itch to try again. I think I am nostalgic for getting something I want to see in my mail box. Are any still worth it on a regular basis?
Weird Tales count? I started picking it up again recently. The VanderMeer's involvement seems to be doing it a world of good. They have easily the best web presence with a daily blog and some audio. I think it's building back into something cool.
this month i actually bought asimov, F&SF and interzone. i've been buying interzone for a while now, mainly because a friend got a few stories into it. as a whole i'm not a big fan of the magazine for various reasons, though sometimes they do do something worth while. i've just renewed my subscription for F&SF, it turned up in border's in glasgow with enough regularity that i started to read it, decided there was enough in it that i liked to subscribe. asimov's was pretty rare in glasgow, so i only ever picked up when i was in london or something. never had enough of a run of it to decide i liked it enough to just get a subscription or not. though the last few issues have suddenly appeared in glasgow, so i've bought them for the "name" author stories in them. analog i never buy, i just never see an issue which has writers that make me pick it up.
Actually I'm pretty interested in this. But it's always difficult (and expensive) to get british or american magazines in germany. We have a publication of this kind called "Nova", three huge issues a year with illustrations of known artists- but, well: It's in german! ;) And I think they're about to change their concept anyway ...
Unless I misunderstood, a recent Escape Pod podcast said that their current subscription rate of 20000 dls per update (and growing) was a larger circulation than all the print fiction SF books except Asimov's.
My sister's got a stack of those old magazines and I've read lots of them, but I've never subscribed and haven't seen a new one in ages.
My mate has a subscription to Interzone and I read it quite alot. Their sales figures are terrifyingly small...
They've run some genuinely good stories over the last couple of years - no recommendations tonight, my memory is blank - which make it worth looking at occasionally. That's just with new writers - Micheal Moorcock had some excellent stuff in there recently.
I don't know - it isn't very consistent, but i'm glad it exists...
I used to subscribe to Asimov's for over a decade. But Asimov's got dropped when Gardner Dozois left.
F&SF was one I got for, fuck, more than a quarter of a century. Yet that got dropped with the most recent issue thanks to low finances and a feeling that reading it was more a chore than a pleasure. I think my reading diet has changed so significantly in recent years that the usual fictional tastes of the future just don't do it for me.
P*S Publishing's magazine POSTSCRIPTS had some nice fiction in its first issue, so I plan to root around for back issues.
I read Apex Digest and Murky Depths regularly. I like both, but Murky Depths' hybrid blend of graphic/comic art and strips and dark SF stories sticks out. On occasion I read others, like Lone Star Stories (which is free), Baen's Universe, Postscripts, Escape Pod & Allegory (also free).
I used to read SCIFICTION before the bean-counters killed it. Once upon a time, I had a subscription to Interzone, but I think in one year I saw one story I liked, so didn't find it particularly good value, and didn't renew. I also had a subscription to Albedo One...not sure what happened there. A newsagents I used to go to stocked Analog, but then we moved. I haven't found anywhere near where we live now that sells the US SFF magazines. Or even the British ones.
I shall spare the board the saga of my subscription to Fantasy magazine :).
Currently, I'm a subscriber to Australian SFF mag ASIM (Andromeda Spaceways Inflight Magazine), and I also read slush for them. Sometimes when an issue arrives I've already read most of it! As I copy-edit for print/.pdf magazine GUD magazine, and am the instigator for their Issue 3, I've read a lot of stories that will see the light of day in the magazine, as well as plenty that won't! And finally, as a consultant editor for British dark SF mag Murky Depths, I get a complimentary copy alongside giving my opinion on borderline stories, and doing a spot of copyediting.
So, along with all that slush-reading, and my regular purchase of Gardner Dozois's Best SF, I'm kept fairly well supplied with short fiction :D. Further, Murky Depths has introduced me to areas I'm not so familiar with--like graphic stories, to which I haven't been exposed since the sad demise of Revolver.
I used to read Omni way way back when. I've had a subscription to F&SF for over a decade now, I think. Usually there's a few stories I really enjoy in it--sometimes more, sometimes less. And I've got a subscription to Apex Digest (to scope out the competition). I catch Strange Horizons and Lone Star Stories and Night Train Magazine from time to time. Most of my short fiction reading is slushing for GUD or doing reviews for GUD (some anthologies and chapbooks and the like, at least).
Asimovs, Analog, GUD, Strange Horizons, Kaleidoscope, Space Squid, Talebones, Tales of the Talisman, several from Sam's Dot Publishing, Fantasy & Science Fiction, Writer's of the Future among others.
