The review page and discussion thread is hideous and painful to navigate. If a site is to be able to recommend $nextbook it has to curate inputs, either as ratings or text reviews. There are huge bookclub memberships but hardly anybody write anything substantial because it's a quagmire to wade through (thus implying few review readers). Lapsed readers like me would love a place to talk books, obscure, trendy or not. r/books is a never-ending loop of "I've just finished Ender's Game and I ..." and "Why we do $something when we read", and similar dross. If there's any space that could use a boost in "user engagement" I wish it could be for readers. But, as we bookish lot aren't terribly argumentative, and unwilling to shiv anyone who opines that they loved DaVinci Code, it's an unknown with what to bait us. I log into Goodreads probably twice a month, avert my eyes and then close tab.
