The topic of audiences was discussed at today's WMF Metrics and Activities meeting.
Looking at https://stats.wikimedia.org/EN/Sitemap.htm, and sorting by editors (5+ per million speakers), there are some language communities that appear to have high participation rates on their language's edition of Wikipedia, but I hear very little from them in meta discussions. Japanese Wikipedia comes to mind in particular, with its large number of primary + secondary language speakers. I'd be interested in learning more about what makes their community's edition of Wikipedia so successful in terms of a high proportion of Japanese speakers contributing to the site, that could be applied to other language editions.
Could WMF direct more resources to studying the successes on Japanese Wikipedia, and how information about those successes could be applied to other language editions of Wikipedia?
