No. Usually I intend to read a book, and if it is good, like Les Miserables, I have visited Jean Valjean far more than once. If it is not, I do the world a favor, and throw it in my trash, usually to be burned the next day.
Usually the text that I choose to unshare with the world has to do with the unworldly and vicious greed I see today. Ayn Rand and Machiavelli are no heros of mine.
If a text is so forgettable that I've actually read more than the first few lines without remembering it, either I, or the book, belongs in the no longer useful section-not that I am a fan of uthanasia, since most writers I read belong there already.
Only the individual may decide what is worthy or not. What I might consider garbage, you may consider gold. It is a great mark of our country that we, personally, have that right to decide.
