We made a thing! o/ @annathecrow and @esgibter and I have been working on a site at fandomstats.com (which I will talk about more in a separate post). But I wanted to share this Bookmark Viewer right now because this post has gotten very popular lately, and this tool is an easier way to see bookmarks of your AO3 works.
It looks like this:
(Known limitation: if your username is something like “Bucky” or “Sherlock,” you’ll get back a lot of irrelevant bookmarks that aren’t actually about your fanworks. You’ll have to view your bookmarks on AO3 instead, one work at a time – just click on the number next to Bookmarks for each work.)
