I run sites that don't have ads. I don't make any money off of them. I still run them. Seems like a lot of people in software development think similarly.
This is the web that I like. Hobbyists and volunteers running low-fi websites for common interests. I'm not against commercial sites like Netflix but don't think every last blog should be monetised.
How do you pay your bills? If running those websites were your full time job, would you still be okay not making any money off of them? Or have you just decided that only people who have other income should have websites?
