> It's very natural to write, and easy to type. You start with super-short examples that are easily understood, using a bare-bones editor. Explaining blocks and iterators is a challenge of course.

Same can be said about Python, Swift, JavaScript, Lua, i.e. any high-level language polished and mature enough.

And an anecdote for you: my kids tried some of the above, they liked Lua most and Ruby least of all. Why? I guess the question is as complex as why some games are more popular than others, there is no clear explanation to these things really.
