Ask HN: Do you read articles on HN before reading/writing comments?

I've heard a couple of times of people who, when they see a interesting submission here open the comments first, then if it seems interesting, reads the article after. And recently, I started thinking that if some people do that, is it not also possible that people are commenting without opening the article, just based on the HN title?

How do you usually interact with the submissions here on HN?
