Hell, I have never seen a ReactOS installation in the wild, and I'm the kind of person whose friends install Haiku, Nix and NetBSD as their daily drivers. And the second-hand stories I've heard about people who did install React was basically "I was bored, I put it on a drive, played around for 5 minutes, and wiped it."
But that doesn't discourage them. Meanwhile, work keeps going on in the background. So many untold man-hours of thankless work going into the project, and the vast majority of that "hard" work with no payoff for years.
And now it's finally getting close to actual Windows, after decades of work, and soon (well, years, but still) people will be using it everywhere as a replacement for Windows.
This is one of the most important software projects in history. My hat is off to the ReactOS developers, and congratulations on the latest release.
