Given it’s a website mostly for experienced computer people who, like you, don’t really need those visual cues, don’t you think adding them would be superfluous?
It's a website for experienced computer people, and I appreciate its minimalist aesthetic, but that doesn't mean there's not enormous room for improvement.
Yes.
> Do you ever get confused navigating this website?
No, because I've been browsing the web for a while and know that every website does things their own way.
