Some of us have built real communities over there, full of people we know and like. Those places have lasted years, and it’s like Cheers.
I do not fault people for wanting to keep that alive. And no, moving hundreds of thousands of people to a new platform isn’t feasible, especially when some features like private communities don’t yet exist.
No, but in this case it’s not just population. If some potato farmer in northern Asia sees a UFO (especially before the proliferation of smartphones), how would it be reported and appear on this map? Lots of other reports come from pilots and such and again, far different distribution between continents.
