And the stuff in anthro books, unless you were taking something more than the 101 I'm assuming you did, was historical -gamy stuff, not quite the same as what's being practiced here and now.
You're assuming the spokes are mono to the hub, and that's all there is for them. Or maybe they can go through the hub to other spokes. I won't say that there isn't a partnership that functions like that, but it is a very narrow implementation of polyamory (which isn't wrong if it works and is satifactory to the parties involved).
You should be thinking more like a web or network. The spokes are actually their own hubs, who have their own spokes who are actually their own hubs, and so on and so on. If someone is an actual spoke, it's because a) they're trying it and haven't discovered being one isn't for them, or b) are happy with the arrangement because it fills that need in their life to the degree they need it.
