I wish there was a service that shows HN pages with short previews of the linked stories included so that you had more info to decide whether to click the link, or go straight to the comments, or skip the story altogether.
There’s a bot on Reddit that automatically posts summaries of long articles (/u/autotldr). Looks like it uses the smmry.com API, and it works quite well. Something similar for HN would be interesting.
The preview should ideally be a summary for it to be useful. Many articles nowadays seem to stretch the topic a lot more than is necessary, with the paragraphs at the beginning being a lot of fluff.
