The number of articles is a terrible metric of the quantity of content of a Wikipedia. A far better way to measure this is to look at the size of the data dumps of http://download.wikimedia.org http://download.wikimedia.org (compressed so as to normalize differences in information density between languages). (Shameless plug: I tried to do that three years ago http://a3nm.net/blog/wikimedia_projects_by_size.html http://a3nm.net/blog/wikimedia_projects_by_size.html -- it could probably be done again today, though the code would probably need to be refreshed a bit.)
