I'm just happy that B&N apparently kept the titles up and didn't leap onto the censorship wagon.
Amazon, in my opinion, should stick to the legal guidelines for their various stores and stay away from vague "moral guidelines". But that's my opinion.
Frankly, if they're that concerned, I wish they'd make it easier to filter out the erotica titles when browsing all the new Kindle titles for the week. I can't browse the Kindle store (or B&N, to be fair) at work anymore because the cover images are explicit enough to by NSFW.
How hard would it be to allow a user modification saying, for example, "Never show me Erotica titles nor Christian Romance nor Paranormal YA." Or whatever. I think not hard at all, but I'm a programmer and not a marketing major so what do I know.
