Well, cost relative to potential revenue. How many people are going to spend maybe $5/month for a monthly magazine. (And that's probably low because the print advertising market is almost certainly not there any longer at anything like the level it was.)

I definitely will if one magazine costs less than 10 bucks and I can afford bi weekly subscription. However I do understand it's just my own opinion and also it's difficult for the magazine to shine in the sea of free material on the Internet.
