why should a subscriber subscribe to more than one hub

Why should a subscriber subscribe to "more of these"? It would be more interesting to know how to pick a hub out of this list (always first might not be optimal).
@julien51 do you have any recommendations here?
Fault tolerance and redundancy is the main reason for this. If for some reason the hub in the middle fails to propagate the update, then using multiple independent hubs is a way to increase the delivery likeliness.
Thanks julien! I've added a note along these lines to the draft!
