Black Gate PDF
I want to thank everyone who wrote in to comment on the question about whether or not they were interested in seeing a PDF version of Black Gate as well as a print version. John and I are now talking seriously about making an issue available as a free PDF so that people could see what the magazine looks like, possibly even the upcoming issue 12.
Has anyone out there heard of another magazine trying this, or been involved with that kind of effort? If so, we'd like to hear about it.

Ideomancer is on the web and has a compiled pdf version.
Hub does pdf, mobipocket, and microsoft reader - but all of these are free magazines. They might have some advice on doing the formatting, though.
A sample issue is a nifty idea, but no reason you couldn't sell a pdf/whatever electronic format the customer wants version, too.

I actually think of BG as a quarterly illustrated review and fiction anthology, not a magazine. To me, it is a book subscription. In light of that, I think really good models of free e-books as sales hooks for print versions are Baen Books and Down and Out in the Magic Kingdom.
Cory Doctorow has a good justification for the use of free long-form e-materials: http://www.locusmag.com/Features/2007/09/c
I hope some of this helps, even if I can't point to a magazine that does it. Of course, there really isn't a magazine like BG on the planet.
Blaze that trail.
So someone else you could talk to for advice, perhaps.
Asimovs/Analog/Fantasy and Science Fiction and Interzone of course all sell single issues and subscriptions at Fictionwise that work very well.
IGMS is doing a couple free stories per issue for the next several issues.
I LOVE the occasional free issue and as I said, I'll pretty much go PDF (or other online format) if it saves me money. I prefer to buy on a per issue basis rather than a subscription.
Baen also tends to have at least one editorial for free per issue. If you give nothing else away for free each time, the editorials are a nice touch. Gives a feel for the editor(s) and what they think of the issue. For some reason I will always read this when it's available.

Paper, not PDFs
As someone who has a story scheduled to appear in BG #12, I've got to speak up here and say that I don't want my work appearing in a PDF publication--UNLESS the magazine also comes out in its standard paper version. I've waited three years for my story to appear, and the thought that the issue becomes a free giveaway on the web is a hard pill to swallow. I want my work to appear in beautifully produced print editions--and that's what each issue of BG has been so far.
I think WEIRD TALES has the right idea--instead of making whole issues avialable online, they take a few stories from each issue, for a limited time--and also they occasionally have web-only stories that you won't find in the paper magazine. This seems to be the best model to follow, as it doesn't devalue the printed version of the issue.
And that's my two cents...

OK, my bad
