I posted it mainly because not everyone on HN is always aware that ReactOS exists, the thread shows up every year or so, and you always find someone learned something new. I also love the engagement around the subject, sometimes you learn something new about the project.

I, for one, just thought of ReactOS again 2 days ago after a large gap. Perhaps the Zeitgeist is presently weighted toward ReactOS. Can't possibly just be my own confirmation bias, because I'm a rational thinker, you see.
