Comment by dang

Can you please make your substantive points without snark or swipes? This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

There's a lot of good information here but the comment spoils itself by coming across as aggressive in this way.

This is particularly a problem when responding to someone else's work. We need commenters to point out problems respectfully, not put down what other people have been making.
