You were downvoted for two reasons. One, it's not civil. Two, it does not contribute anything to any discussion; it's conversational noise. Explaining what you mean is not "justifying the obvious". It's starting a conversation.

True, I'm being cranky. Genuine feedback usually looks pretty cranky, I figure. Most people will close things that aren't immediately understandable.

But you see the problem in the other comments as well: it's "cool". Which, in the real world, usually translates to "unusable".

The author of the website isn't reading HN comments for feedback. Your feedback is better placed elsewhere.
