How and Why Companies are Using Ruby on Rails: The Thesis!
Michel Barbosa is a bachelor student at the Erasmus Universiteit Rotterdam in the Netherlands and has just completed his thesis: "Delivery of the Key Adoption Factors and Key Characteristics of Companies Using Ruby on Rails." Or, in layman's terms, he's produced a document that goes into the hows and whys of how companies have migrated over to using Ruby on Rails.
There are lots of graphs, charts, and tables, so enjoy!
