Some tangible things I'd lose: - I read a lot and so friends not-infrequently come do me for recommendations. Having rated a big chunk of the things I've read, I can sort by rating and scroll for things they'd like. Often I go "holy shit I forgot all about that one, but it's perfect for Bob." - I'm always looking for the next thing to read, and it's really nice to be able to quickly scroll through my (long) 'want to read' list for something that piques my interest for the mood I'm in.
