when I showed it in public in an event, I saw the same loop many, many times:
1> user press buttons confused, see I am standing nearby, ask me what they do. 2> I do nothing if they have a SO near. 3> SO points user, that there are descriptions of the button right there in front of them. 4> User slaps his forehead.
In case there was no SO near, then I would point it myself, the reaction of people was still the same...
I concluded that ins't just that people don't follow instructions, is that they don't even try.
