Just noticed this comment a few posts back from "i mate." Thought it was very much to the point:
"It's fine to initiate an event for people to 'come together'. but if there is no exploration of the ethics of an 'encounter', then it's like never starting a fire. for people to really share and touch each other there needs to be friction, and friction comes with one being vulnerable.
Your work should explore its psychological dimension if it should claim to fulfill its mandate."
Not sure about the 'psychological dimension' but friction and vulnerability are directly at the centre of the search.
