A vain moment where I am quoting myself from the thread on the new book page display (nope, they are not putting all editions, genres and shelf displays back).  If you missed that one it's at https://www.goodreads.com/topic/show/1648001-book-page-design-change?page=1 

[UPDATE AFTER READING ENTIRE THREAD:  Okay, I should not have quoted myself.  Becky brings up a better point in message 48 -

"Yeah, I really can't imagine why anyone would want to navigate to the review page just to see the shelved date, when it was always easily visible from the community reviews.
It's useful to see how many people added a book on a specific date, as well. Sockpuppets will love this change, I'm sure."

*sigh* the date rated/reviewed being suspicious was always one thing that alerted me to potential sockpuppets.  Change hasn't actually rolled out to me yet, so in my defense, I was just looking at screenshots.]
