Olson's comment is directed at the reality that so much of what is passed around -- published or not, performed or not, optioned or not -- is garbage, but what he's really saying is that readers are justified in not reading for the sake of reading if the material doesn't speak to them for any reason whatsoever. It doesn't even have to be garbage; it just has to be "not for me."
