I build stuff that people use every day (judging by the flood of tickets I'll get if I ship a bug), but my public github profile looks like a ghost account. 99% of what I build is proprietary, and is either in a private or self hosted repo.
I'm not sure scanning public GitHub is a great way to identify "do nothing" developers.
Yeah, I agree, but since it hosts a huge amount of work done by many of us, maybe that's why it was used as one of the sources.
Hosting and public are different. This measure is like saying unless you are painting public murals you haven't made real art. The take is just so wrong it's hard to know where to start.
The article is all over the map. A script run by one person is "real" but implementing a front end is not?
I have, numerous times, written significant portions of a various features within much larger products.
