The typical class of HN user is constantly chomping at the bit for something to get outraged about. The number of teapot tempests I have seen here is positively insane. People will get angry and start demanding executives' heads based on nothing more than vague hearsay and a misunderstanding of the law.

I'm sure the broken clock of HN opinion gets it right pretty frequently, but I wouldn't say it has strong predictive power for whether something bad actually occurred.
