Edit: Apparently somebody agreed and removed the clickbaity 'Snowden' from the title. Thanks.
If you determined whether an article was clickbait or not based on HN comments, you wouldn't read anything, ever.
I'm skeptical that this community has a handle on what "click-bait" is. Anything that isn't written in the precise style the commentor enjoys, or isn't as information dense as a commentor would like seems to gain the label.
