Agree with this premise, Users will not necessarily appreciate simplicity over functionality. It's also worth noting that Facebook, Craigslist, Photoshop, etc are not necessarily optimizing their UI for new users, but rather those users who have been using their software for a while. I imagine that one's design considerations will change based on the prototype of the typical user.
