Open source is a good thing, since you can involve other creative minds besides your own, development can move so much quicker.
That said, "getting paid," is the Achilles of open source, and if something is not done we will lose our best and brightest authors because it's just not financially prudent.
I have a similar problem over at my on line motorcycle magazine, The Biker's Garage. I put a considerable effort into my magazine, but, it has yet to earn any real money. I can spend days generating original content, making photographs, researching, writing. It's actually quite a time drain. It's been doing well in other ways, I'm seeing six to seven thousand visitors a month, so the content is useful, and popular. The downside is money, I have Google ads in the side bars, and I just picked up Amazon, fingers crossed I get some sales there.
I think the issue is that my readers don't know how I make money, they don't know to "click out" on a Google ad leaving my site, and they don't understand I can make money from the stuff they buy on Amazon. Perhaps they just see the ads and think I'm being paid for them like in a print magazine.
I'm at a point where I'll have to decide if I will continue or not. Nobody will feed me for free, so I have to make a choice where to spend my effort, my web development and SEO work, or the magazine. I'm considering actually writing an article, "Support The Biker's Garage," and lay it all out in regards to the money, that way people can understand and choose the "correct" action to take.
They always say "You get what you ask for." So I'm going to ask, I suggest you might want to do the same. Personally, I think a suggested donation of 1.00 USD is not too much to ask.
