So that we are on the same page, I want to distinguish between three different components of HN that tend to run together.
First there is the news event [1]. This is just the fact that Rice has been named to DropBox's board [or more abstractly that it has been reported as fact]. We both agree that this is relevant to the HN community.
Second there is a particular article [1] submission to HN [or several particular article submissions] related to the news event. Again we both probably agree that most or all of the various articles are appropriate for submission to HN because the news event is relevant and furthermore the news event is not likely to receive attention in other media proportional to its interest to the HN community.
The third component is the comments that are made on a particular article submission and it is by this third component that many in the HN community judge an article submission as a contributory or detrimental. When those members see an article submission as contributory, they may upvote it [yes, people upvote article submissions because the comments are good]. When they see one as detrimental, then they are likely to flag the article submission. And although there are members of the HN community whose experience leads them to flag article submissions the fear will lead to detrimental comments, they do not appear to be the majority.
[1] Using the word "story" tends to conflate both of these.
