I often click to read the HN comments first, because they are often full of insight and interesting links. (This is also why I read HN from a custom #newsyc channel in our work Slack that posts links once they hit 20 points: it allows time for initial comments to accumulate, and Slack helpfully keeps track of "new" posts.)
Simply bookmarking the article itself to read later would not be as useful to me personally, but I bet there are lots of people who would find your approach helpful.
