As of the date, Monday, July 18th 2011, only 6 people have added 100 categories to pages. Of these 6, only half have added 250. Only one person has gotten the achievement badges for 500, 750, and 1000 categories.

Yet some people have done at least 500 edits since the badges came, only I have done 500 categories, let alone 1000. Which is sad because I joined sometimes earlier this week. Together we can link the world of Civilization Wiki as one... or something.
