"Fifty Shades of Grey" Library Troubles

It seems there's now a controversy regarding that lovable, sometimes laughable, and always fascinating phenomenon called "Fifty Shades of Grey" that's taken almost everyone in publishing by absolute surprise.

Though I don't have any strong opinions about the writing because I see writing changing and evolving ALL the time these days...in other words, readers seem to LIKE certain things that wouldn't have been done ten or twenty years...
