Yeah. I have no doubt that developers are a much larger proportion of Linux users (approaching 100%) than they are of Windows users. I suspect that may also be true for OS X users. But there's simply a huge, huge number of Windows users and consequently, a huge, huge number of Windows-based developers. Not necessarily bound up in the Microsoft ecosystem (.NET and the like), but developing on Windows. But HNers, who are bound up with a tight-knit community that consists mostly of open source software, Github etc., quite naturally assume that they are representative. (Sidenote: Git and Github also have minority version-control market share. I would not be surprised if the biggest version control out there was no version control at all.) In reality, I would be shocked if Linux/OS X-primary developers constituted more than one-third of total developers. Unfortunately, accurate statistics are hard to come by.
