Medium didn't pay me to post this article on HN. I'm its author and I figured it could help some people.
Anyway. How is it not a good article? Is it obvious for people to use window managers? Is everybody aware of their existence? Was Medium not the right place to post it?
Medium is probably the perfect place to post it, but that doesn't mean it's relevant to HN. What part of the HN audience did you predict would be helped?
