The move towards booktube content seems so disingenuous - basically a huge stack of books that she's heard are popular or that 'other people' are reading. If anything I'd rather not see the same popular books reviewed again and again, there's enough of that already, done far better by other people. She's also missed the boat for most of what she showed, the majority were popular a year or two ago by now and most people who care have probably already read them.
Imagine asking people not to try and add her as a friend on Goodreads but wanting them to follow her there to boost the numbers though, such a snotty thing to do. I'm not convinced she has a passion for reading any more than she does Harry Potter but I suppose books fit the bill for easy, relatively cheap content you can churn out without leaving the house.
