Hi!
I've made a tool to find users with similar favorites! It's available here: http://finde6users.ddns.net. You enter your e6 username (case-sensitive), and if you're in my database it will list similar users. More details on this reddit post.
It's really a prototype for now, and I don't promise to keep it up indefinitely, but it can still be useful.
However, you're in my database only if you had at least 32 favorites with at least 90 score, at the time I collected my data.
Which leads me to my question: does anyone have a complete dataset listing favorites to share? Or know how to build one efficiently? For now I've been using a small subset, by calling /favorite/list_users.json on each post. But if I want every favorite, that would take months. So if there is another way, that would help a lot. It doesn't have to be up-to-date either.
