I don’t mean to suggest you did anything wrong. If you’re on mobile, perhaps you meant to close the keyboard and hit an autocorrect suggestion instead and didn’t catch it before submission? That seems like the most likely explanation that comes to mind.
Somewhat off-topic, I’ve noticed on HN that sometimes comments end with single word on a newline, like you have done here.
Did your comment get truncated somehow, or did you mess up a copy/paste, or what?
Has anyone else noticed this? Is this a telltale sign of generated comments, or other tool usage?
I’ve only noticed this on HN, and maybe Reddit once? It happens somewhat more regularly than I can attribute to mere coincidence or accident.
