It is really great tool too see what used to be very popular posts in the past.
I have one observation. Posts linking to twitter - https://deephn.org/?sort=score&filter=%7B%22score%22%3A%7B%2... - have most of the preview occupied with navigation and other not interested parts. So maybe it is possible to use some hacky solution to show the content part for the most popular websites, or if multiple pages are downloaded from the same domain the content part could be detected automatically.
