readers have definite expectations all the same, and they search for certain information in particular places. If these structural expectations are continually violated, readers are forced to divert energy from understanding the content of a passage to unraveling its structure.
This is definitely true and I feel like organization in an article is key for the reader to find the information they need, but there are times when I don't look at some sections since I do not know what it fully means. I wonder if it would be noticeable to readers if a section that is not viewed often was not meeting these expectations.
