I was going to say it's like "gamifying" books, but the attitude is even older than that. It reminds me of people who will pick what games to play based purely on reviews, like their optimizing their Aggregated IGN Score Experiential Index.

I had to try to stop myself from doing that, because I would end up forcing myself to finish every single book I picked up, setting page count goals for the day, and not re-reading books because it cut into my goodreads goal for the year. When really... you should just read what you feel like, and for it's own sake, and not really worry too much about intentionality.
