Hub hub hub

So I am still hung up on this idea of a hub and therefore am going to explore it further now. Today I was thinking about how the museum serves as a hub in many ways- as a place to exhibit work, as a social space, as an educational center, I could go on and on-- but the one aspect of all of this that I don't have a satisfying answer for stems from a conversation that I observed as part of my thesis fieldwork where someone was addressing the idea of authenticity. While this particular conversation was in reference to teen programming, I think it applies here as well- if the museum can serve as a hub, defined by The New Museum as, "what it means to displace conversations and activity from elsewhere to New York", is it an authentic one? What contributes to its authenticity or lack of authenticity? Is The New Museum an authentic hub because someone decided to call it one or is it inherently so? I can't get off of this hub concept-- can't you tell...
