I've chat with her several times on steemit.chat. She is remarkably intelligent and has knowledge in many different areas. The way she responded in this post is consistent with the conversations I've had with her. Her food and travel posts are written to a style consistent with the material and the audience she is appealing to. These posts do not need to be expressed in an academic style. I also adapt my style depending on the content and audience. I don't think that is particularly unusual.
