There are some communities where the vast majority of posts are by on or two users reposting news articles.
Sometimes they’ll summarize below, but they will almost never share their opinions on the article, or even just ask what others may think about in regards to this aspect or that aspect. So the entire feed is just URLs.
I would feel more engaged to comment on those posts, or even start a post in the community, when it doesn’t feel like a bunch of robots reposting the daily slop.
It’s better to share links then it is for everyone to constantly substitute the article with their spin on it. Youtube has turned into thousands of “commentators” summarizing the original article with their personal opinions. One could argue that it amounts to content theft.
