Saying "thank you" and upvoting is encouraging, and makes communities stronger. Blaming people is discouraging, and divides communities. Criticise the article, not the author, and thank the author for what they got right (a good topic for discussion) so they'll create more in future. We can also increase trust in the community using links. Mentioning names in a good way is particularly helpful, like academic citations. Thank you for finishing with the "great tl;dr", xcambar, you're asking the right questions :)
