To me, the article is useless. It brings no value. Writing and talking about different type of fluency will not make anybody fluent. It just creates a new problem in people's mind. "Oh, there are so many fluencies. There is a lot of to do. I must set another goal, go for it, work hard! OMG, help me!" ... it is ridiculous and stupid.
Also, this article is confusing. It says:"Well, actually, I can’t tell you what fluency means. The only person who can tell you what fluency means is you." It sounds like those positive sweet talks "you have the power! You are the hero! You can change the whole world!" Then she describes what perfect, quick, native-like, literary fluency mean.
