I think that's not a problem with significant whitespace, but the problem with CoffeeScript syntax. I'm programming in Python and had been programming in Coffescript and I always found Coffescript code much harder to read than code in Python. I don't know exactly what causes this, but my guess is that indented blocks of code in CoffeScript can appear after any line, so you don't have visual anchors that will indicate where one block begins and other ends. In Python however, indentation is always comes after keywords like def, if, class, for etc... and those are always highlighted by your editor so your eyes can always catch the block start very quickly.
