A long time ago I lived in baltimore, and there was a man who was "homeless" (he lived in the church he sat behind so he had a bed) who did just this. You would give him a book of yours and he would give one back that he though you would enjoy... It was like having a one on one book club, with the greatest recommendations ever. When I moved from baltimore I gave him the dozen or so books I had to add to his collection, and I always wonder what ever happened to him. I miss having a commute (walk actually) that included the strange bright spot of his presence.
