I see where you'e going with this, but I might change your examples a little bit. There's a very fine line between just a simple Google search and a lot of what you're showing there. It might make sense to demonstrate something that requires more human intervention. The file conversion example is a good one, and maybe expand more on assembling trip itineraries, etc. IOTW, things that actually would take up a lot of time, where the value of the site would be more clearly demonstrated.
Your point would be more clear if the article wasn't troubled with spelling and grammatical errors. Just like a programming language, English has a syntactical and grammatical form for a reason: it makes it less likely to be interpreted incorrectly.
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.
I've had adsense sites making a few hundred $ a month since 2005. Its hands off to the point I don't even know what they made until I get the 1099 from Google each year.
However every (or nearly every) business that makes money truly passively is an under performer. They are like boats without captains that have not sunk yet. Those same sites, along with the A list domains some are on should be earning $200k+ a year by now.
In that sense, I would define passive income as doing a terrible job on a stellar business model.
Of course, there are also businesses employees or partners can run. Those absolutely can be done. I have one project like that right now. But, just like a dividend paying stock or bond, you are going to have to put in a serious asset to minimize the chance of the people running the show from fleeing.
I have passive income thanks to Adsense, in comparison with the average salary in USA is kind of low; but is bigger than the average salary in my country (Colombia).
And I also want to point out that nobody is talking about "wealth" around here, just about a few more bucks.
I would hypothesize that It's because they are easy to find/submit. It's a lot more work to go to some obscure blog and find some really great article then it is to open up news.google.com find a top trending story and submit it.
