There does not currently appear to be any indication that there are any comments on news items. Also, it's not intuitive (to me, at least) that I could make a comment by clicking on the headline.
There should be some indicator (e.g., 0 Comments) somewhere associated with each news item, which could also be a link to the comment form and to view other existing comments.
I added a comment to news:3.
Fixed in 2763 and deployed.
