But I'm also really curious if there are big Wikipedias with nice stable ~linear growth. So far Chinese is the only one I've found (I just randomly picked 7 languages for initial analysis), and rather than poison myself with data, I'll set up a proper experiment and see how many other Wikipedias may have linear growth. Then I'd want to see if that linear growth did indeed indicate a vibrant community or if the explanation was seedy (spam, edit wars, etc.).
