I second this. It baffles me when I see an article with 100+ karma and 5 comments. How can something be so interesting and yet spawn so little discussion? It makes no sense.

As pg says, those are usually very good articles. I'd say the first impetus to comment is to correct, the second to add relevant detail. When the article doesn't need either, it's good.

Not at all. I can see many instances where an "upvote" is a stamp of approval--almost like applause. Discussion is not always necessary.
