I didn't see anything about payment. I run both groovymag and jsmag - monthly PDF publications - and I share the pain of finding and curating good content on a regular periodic basis.
With that, one of the challenges I've had is that in some cases, some authors who might otherwise contribute won't because of the pay we offer. Those for whom payment is a concern end up needing to prioritize our articles lower than other commitments. I'm not complaining - I understand, and have been in that situation myself.
I didn't see anything on CQ about payment terms beyond the writer guidelines:
"Well, we’ll pay you. At the moment we’re not sure exactly how this is going to work, but the basic idea is this: We hope to make money by selling PDFs, print-on-demand books, and ebook versions of our pieces as well as from subscriptions to the print quarterly. That’s revenue. It will cost a certain amount of money to produce the Quarterly and run the web site, etc. That’s expenses. What’s left over is profit and we will split that with you in some equitable way."
For better or worse, with groovymag and jsmag, I committed to paying authors and putting out the issues before I necessarily knew I had paying customers. It was a gamble, pure and simple, but it's worked.
I'd talked with some other people who had suggested (and wanted to pursue) community publishing which would share 'profits' of magazine sales equitably with authors. Interestingly, very few of the authors I spoke to (basically 1) had any interest at all in that. The ones who wanted money just wanted to get paid, not wait around for weeks or get quarterly royalty payment checks from back issues. They just wanted to submit a piece and get paid. Fair enough.
The push for 'community sharing of revenue' doesn't seem to come from the authors that I know. Certainly, if we were talking about numbers with a couple more zeros at the end, they might care, but even people who write long form tech books generally don't do it primarily for the money, as they know they're not going to retire on royalties from a book on CouchDB.
P.S. - if you're interested in contributing pieces on advanced javascript or groovy, ping me at michael@jsmag.com
tl,dr - CQ might have taken off had there been an up-front commitment to kickstart the chicken/egg problem of content/readers by greasing the wheels a bit with some initial purchased content.
