Most articles/videos on sites like HN fall into this category - I wouldn't have paid to read this article for example. To me, this comment thread is worth much more than the article itself and I don't see anybody here upset that they aren't getting paid to comment.
I guess that means that I would probably pay a subscription fee to a site like HN but that I wouldn't generally pay for the content itself, which does seem a little backwards. Still, that's what's valuable to me. Does anybody else feel this way or am I weird?
