I am preempting another Work In Progress post by putting up this map. This indicates the top 500 cities that are using the Alfresco wiki and forums, which we think is indicative of who uses Alfresco. It shows that the usage of Alfresco is truly global in nature, but naturally follows the cities that are big users of enterprise software. Still we are getting to places that are relatively new to enterprise software. This definitely shows the power of the open source model.
I'll be writing more about the "Colonization" of software in general in my Work In Progress posts.
