I also agree that it can be a bit nerve-wracking to think about it all getting lost by some random person I can see the appeal of doing this online so everyone can see everything as it progresses and not worry about it getting lost!
The travel journal type that was first mentioned ~ where you send a journal all over the world ~ has been incorporated in 'geo caching' ~ This might be a fun way to have a journal that travels and you can actually meet many new people
