I dislike Ruby and have written about my issues with the language at length, but this is rarely a productive discussion to have. People work with whatever language they have to hand unless they are explicitly setting out to learn a new one. Almost certainly seven years ago the author was using Ruby as a central tool of their work and when they started a project just did it in whatever was in this toolbox at the moment.
