OT: perhaps that guideline should be updated to say that when asking a question that appears to be entirely covered by the article under discussion, commenters should clarify that they have read and it, and explain why the article does not sufficiently answer the question. As it is, it's just a suggestion to be more passive aggressive - those two examples convey exactly the same thing except in the second one, you pretend that you are not accusing the commenter of not reading it. For example here, my response could have been "The very first paragraph says that." Would you have interpreted that differently in any way?
