Why does the HN crowd love to leave comments of mean criticism as if it was certain the creator of the submitted site wasn't going to see it? You can levy critique without being rude. Not many are doing this, but it doesn't take much. Maybe letting harsher-than-necessary criticism wash over you is necessary for putting any creation out into the world, but it still feels bad to see.

This is why people outside this community often dislike their work being shared here, or at least refuse to read the comments.
