We need a good name for a collection of seasteads attached together to form a village or city. "A pod of seasteads" (like a group of whales) has been suggested, but I’d like to hear your ideas. "An independence of seasteads"? We could take the name from my proposed festival: "An ephemerisle of seasteads".
Or if one is pessimistic, perhaps "A target of seasteads" :).
