Miguel,
I appreciate what you're saying but I should also point out, gently, that your metaphor about stirring the pot is exactly the kind of vague advice that left T with no clue about what actions to take next. Trust me when I say that at that point in time, "Just add three sub-points" was the correct play.
The good news is that T took that advice and used it to improve vastly at our brand of academic writing, to the point where he can now easily grasp your meaning the same way that most well-developed writers do, and can easily find ways to implement it to improve as a writer. Like I said, all a good climber needs is a handhold in the stone.
This raises a point that I think is especially important to this article; the type of high-level, metaphor-based advice like the stuff you offer in your comment is great for well-developed writers who can understand its intent and implement it creatively. However, it is really not helpful for early-phase writing, which is why I put together this article in the first place.
