It's a fair comparison, Ed (though I never think good ol' paper magazine is something that we could be replaced. It's just a different reading experience).
Let's put it this way: This is the only way Hacker Monthly could move forward and sustain.
Don't get me wrong. I love working on Hacker Monthly and enjoyed every seconds I spent on it (this came by surprise, actually). I love sending email to authors asking for permission (and sometimes have a lil conversation), spending days after days on the design, curating articles and so on. I love it all, except one thing, it took too much time.
The money we made on the past issues (advertising + print magazine sales) is, simply put, so little that it could not justify 10% of the time we spent on making for the magazine. I have to spent the rest of my time working freelance contract work to pay bills. And honestly, the past two issues wouldn't be made possible without the voluntary help from Ricky (who worked so much more than just a proofreader, thank you!).
We believe Hacker Monthly provides so much value for the readers that we could charge for it. The subscription revenue would enable us continue to produce really high quality stuff for years to come, without burning ourselves out.
I hope that explains well.
