Like every other dedicated reader I know, I keep endless and ever changing lists of books to add to my "to be read (TBR)" pile, and I rely on my reading friends for some recommendations. But what I really love is the serendipity of simply stumbling across a really good read. It's a blissful experience. BookCrossing seems to me to be the ideal agent to spread the bliss, and to give seredipity a little nudge. And I think it'll be a real kick to see where "my" books end up. Chances are some will end up being far better traveled than I'll ever be. How cool is that?
