I know that DHH did not create Ruby. My goal was just to show that looking at the people who build a language ecosystem helps to better understand the tools themselves.

Rails (as one of the main use cases for Ruby) definitely influenced the direction of Ruby as well as what the community regards as a typical Ruby code base.

That said, I can see how mentioning DHH might come across as misleading, I should have added more people to the other language/platform examples as well.
