That appears to be discussing the problem of free will, while assuming that you already know what the problem is, and more importantly what "free will" means. My problem is that I don't know what the very concept of "free will" is, completely separate from questions of whether humans actually have it or how.
No, the concept of what free will is is actually exactly what the series of linked posts is meant to address. Read the first, http://lesswrong.com/lw/no/how_an_algorithm_feels_from_insid..., in particular. "Free will" is a term with the same properties as "sound."
If I understand that analogy then it's basically saying that "free will" is an excessively vague term that evaporates entirely when you describe what you're thinking of more specifically. Which is basically what I'm saying: I don't think it's a coherent concept by itself, and I don't know what people mean when the use the phrase.
