I think I remember every single book I have read that's worth reading, and that list is in the hundreds. Not because my memory is so good, but how do you forget if you actually thoroughly enjoyed it / got something out of it? edit: I don't have a goodreads acct and don't fully remember what it is, but I think the value there is finding people who like books you like, especially less famous ones, and then finding what else is on their list.
