Hmm, does that bring about another concern? Not regarding Karen and David, but (kind of like Carol said above) couldn't people with large twitter followings get on a campaign with their platform to get a bunch of high ratings just to land them in the shop? That can't be a good thing, can it? Amazon must be putting something in place to prevent that. If, that is, in any way how they're stocking. They might just buy in like any ol' book store and then use the book ratings on the books they've chosen to stock.
Also, @Jason Byrne
it's funny you should say Keanu Reeves. I just had a glitch in the braintrix (deja vu). I wonder if this is another sign! I'll be on the look out for twins!
