Three notes: 1. These tweets aren't teaching; they are a teacher asserting her authority. Looks like teaching, but it isn't. 2. They aren't very good tweets. There's nothing memorable in them, nor concision, just reduction to the simplistic. 3. They sanction a misunderstanding of writing, and of teaching and learning. In a tweet, they fail to enact what they assert. And a comment: What do you do the second day of class?
