The problem at Goodreads is not that they haven't made any improvements over the past decade that Amazon bought it. The problem is that they've only made technical improvements and other changes under the hood that no user ever notices. They weren't able to drive a strong product vision forward under Amazon because of poor product vision and poor organizational incentives. It should be a cautionary tale to the people who always complain about not working enough on tech debt - too much of that can be fatal too.
