I used to have them, and then I realized that if I felt a rereading need I could almost certainly get them out of the library. :-) It's kind of nice to be able to get popular books out of a library instead of having to own my own copies.

And as far as bad writing goes, I like a lot of books that are not well-written. People seem to be surprised by this, but I'm not sure why--I often read books for particular buttons that they push (siege engines! giant stompy robots!), not for deathless prose. If deathless prose comes along for the ride, then, excellent; and if not, well, I'm pretty content without it.
