Thanks Steve. I have been thinking about it. But it does not fit my long term business model. I am developer and want to make web and software development my main income source. And as I want to make it passive I am doing it by putting ads on free content or software (to make it long term income).
If you want to be an entrepreneur then you better go where money is. Besides how do you expect web development to function as passive income source? Offering a service/application may be such an opportunity - but then you're an entrepreneur who uses code to leverage his business.
BTW. Your project is mint - love every installment of it!
This ebook has been done "by accident". As a developer I want to make passive income from selling many copies of application or via ads on web pages/in software.
If you do go the ebook route (and if you keep blogging at your current pace, you should certainly have enough material), check out fifobooks.com (disclaimer: my startup runs that site).
You want to make web and software development? Fine. code up some a/b tests for the page, work on some ppc optimization, look for ways to capture email and advertise on there.
It's not sexy. At all. But if it works, then you can focus on stuff you really want to do.
Thanks steve for valuable comments. I am doing it almost all the time. And meantime I am working on projects. Unfortunately I have only 24h per day and I still want to spend some time with my wife and my little kid (1 year old).
