- Looked at "popular" bookmarks, e.g. https://pinboard.in/popular/ - At the far right end of each page title, there's a little number. For example, beside "Lotus 1-2-3 For Linux", there's currently the number 21, which links to https://pinboard.in/url:61d59935774d1affe22713a7423c78bd17ef.... - Following that link, you see who bookmarked that link, with name, tags, and some related other links. Of course, clicking on a user name will show you other things they've linked, at least using the default public setting.
