thankfully
i have yet to figure the benefits of a site where most books have 1500+ reviews which always average out to somewhere in the 3.5-4.5 zone.
I do look at it occasionally via my Fire tablet, but unless you want to be active in its social media zones , I just don't get it.
For a potential book purchase, I find amazon's own book review statistics much more useful , even allowing for fake reviews and other manipulative tricks
