Marc, I was thinking about your "similar mappers" idea. of course, you can make this very complicated (create a dataset of actions by users, then let loose a similarity algorithm). However, it can also be very simple. For example, using this [1] Overpass Turbo query, you can get the usernames of all the mappers who last touched a historic=monument thing. It wouldn't be very hard to do this for a larger area and aggregate by user, so as to see who thee bigger contributors are. It is a crude measure, but it's just to get a list of people whose work you might want to check out, so I think it would do. You might want to download without the geometry and without first loading in your browser when checking larger areas or wider queries.
