Am I the only one that thinks Apple is using revolutionary technology to work toward the perfection of a deprecated computing paradigm? I mean, yes, iCloud makes computing work like magic, but it sort of ignores what post-web computing means . Computing anymore isn't just about working on the same documents on any device that you own seamlessly (that part is, to be sure, great), it's about sharing and collaboration.…
Conceptually, it may be a lot to thrust on a user all at once that iCloud is not only your own personal magical data synching tool, but that it also publishes your data to others, which has data privacy implications. Maybe a gradual roll-out of social features gives time for people to be comfortable with using the existing features without worrying about the social implications of their actions.
