Thanks for the link. I remember the first time i made a really silly comment without reading the full story i was put into place (downvoted ruthlessly) by the community and i knew i had done something terrible. This is the post https://news.ycombinator.com/item?id=2825177. From then on i really took sometime without commenting on hn not because i was angry, but because i was scared of being downvoted. It taught me i needed to get my facts right before commenting on hn however much harm i never meant to cause.
