Reading the original article takes effort, in part because it may be hosted on a slow-loading site with a bad UI, have intrusive ads, be long, uninteresting and / or written in a language that's difficult to read. I wish HN had at least snippet previews for submissions (like in Twitter, WhatsApp or Facebook) so that I could look at them without following a link and decide whether to open them or not based on more information than just the title.
