I don't see passive income like that. I see passive income as something you can gain by spending some of your free time to get recurring money.

Agreed. I think it's better to say it takes time up front. But the upfront work may take a while.

I spent six months last year writing explanations for a standardized test. It was extraordinarily boring. But now I get $1000-$1500 per month in licensing fees.

I think there are lots of passive income opportunities for developers to make passive income in non-technical niches.

For instance, I've only been learning programming for a few months, but I have a Wordpress blog. I'm probably going to buy that plugin. Always wanted to track that, but didn't know how.

That seems less "passive" than just "small". But then again, as the poster noted, there are many ways to define passive income.
