The difference between Wikipedia and Reddit/HN is what I would venture calling 'contribution barrier.'
Think how hard is it to contribute to a Wikipedia article vs. Posting or commenting on Reddit/HN. Let alone voting.
I'd imagine that most of the registered users have voted, and a majority have commented. I don't imagine quite a lot of people have posted links.
If I'd have to guess a ratio of lurkers:voters:commenters:posters, I'd say it's 40:30:25:5.
