My comment about the irony of a free speech post being censured was mostly sarcasm. That said, Hn has a pretty broad set of topics that are allowed through. Right now there's a post on the top page that is just a rant about people being late to meetings. Is this more of the "specific focus" of Hn than "free speech"? I'd argue the opposite since technology is playing such a major role in the censorship of today.
All that being said Hn remains my top visited site (by far), so I am not for a minute complaining about its quality of moderation.
