Now they are discussing how StackOverflow is horrible, and unwelcoming and dehumanizing.
Would I ever put a "hope this helps" in the end of a reply? Of course not! It's so obviously superfluous. Like someone said, if you didn't hope that helps, why the hell did you write it in the first place? But apparently for someone, the lack of the "hope this helps" is insufficiently polite and unwelcoming.
