Once you're #1 on Google searches for half of the published corpus of humanity you stop caring about little things like that... Surprised storygraph even has that many users when they're nowhere on Google when I search books.
I mean I'd bet 90% of goodreads users are just googling quotes but yeah this girl got her timing right, Amazon bought goodreads and then just sat on it for like a decade... Storygraph would never ever be able to compete with goodreads on search, so they sorta had to pivot to winning on social and stickiness.
