You have a point that function calls should look like function calls, but keep in mind that, in Ruby, juxtaposition is how function calls look. The same goes for quite a few other languages as well (Haskell and ML off the top of my head, but there are others).
Yeah, I know it's not totally rational. Groovy does a trick where a Groovy'd Java class hides all the setters and getters and makes them look like property accessors. (C# does that too, I think?) And I like that, so I'm not necessarily arguing one way or the other; or at least I'm not arguing with the blog article. I have this argument with myself all the time! =)
