I didn't mean to say "Python does it, so CoffeeScript is not a problem", but rather that both can suffer from too much indentation. CoffeeScript is a little more prone, given the callback-heavy nature of JavaScript, but similar treatment of surrounding whitespace is helpful in maintaining clarity. (Basic example: I find Python's standard of four-space indentation helps CoffeeScript readability, and prefer it over the popular two-space indentation.) And in both cases, excessive indentation is a useful signal.

Readability is very subjective and depends on the user's knowledge of the language, as well as personal style, or 'accent', if you will. Code written with, for example, leading commas in dictionaries instead of trailing commas just looks bizarre to me and is a little harder to read, to me, even though I like to do something similar and stack colons.
