One thing that came to my mind after the summit was that after John McCann's presentations on various GNOME Shell topics, people went from the so called 'gnomeshellskepticism' to actually start getting it, and by the end of the event most people were using it by default.
A lot is yet to be done to get it to a final state and they seem to have a real vision for it. But it was still bugging me the fact that an explanation of the philosophy and showing some of the features in action made such a difference.
After realizing this I somewhat started to considering that a first login introduction in form of an assistant or a video could make a huge different on terms of success of adoption of the new shell, this approach works pretty well for games, where usually the first time you play it there's some sort of introduction showing you the basic controls and the interface.
