What different projects and success stories do we have for adding geographic coordinates to existing articles in various languages of Wikipedia? In some languages there are WikiProjects, but I think they were more active some years ago.
I tried to count now, and I think the Swedish language Wikipedia has 32,600 geographic coordinates for its 404,000 articles or one coordinate per 12.4 articles. Is that reasonable or is it far below the average?
I need a success story to learn from.
