User blog comment:Brainwasher5/The strange obsession of using "Note the", "Note that", and variations in this wikia/@comment-1187559-20121023051809/@comment-1687225-20121023134251

By that logic, we should say "note that" for every single sentence with a fact, ever. It does not make it sound professional, as it is never used in any scientific or academic journal. You just state your facts. You don't say "note that the Chesapeake Bay is polluted mostly by the agricultural sector" in a memo, you say "The Chesapeake Bay is polluted mostly by the agricultural sector".
