Maybe you should be more selective of who you become friends with. :-p
My 9 year old knows how to move apps and create folders. I didn't tell him, but he saw me do it once. So if we both like a game it mysteriously disappears to be found in his folder later on.
Moving apps and the folder thing are operations people don't tend to discover by themselves, but only need to be shown once to be understand. That's not to praise iOS, it's the same with Android and WP.
I watch Apple keynotes not only to see the new stuff, but get "training" too.
(when icons start to wiggle my assumption is that the first thing confused people would do is hit the home button, which would stop the wiggling)
