Agreed... all the confusion arises when the words hanging and standing are introduced. The chap from the OP explains it well but still managed to perpetuate confusion (and so did I!) by using those 2 words.

The the original question posed by EvilV, does a hub hang or stand, is therefore an incorrect question - it is neither. The hub is supported by the entire structure, ie all the spokes, whether they be infinite in number (solid disc) or few in number.
