I find it surprising that there's 2 Australian cities on here but nowhere from the US. I've been under the impression Australia was similar to US in "Liveability" metrics, for good and ill.

The rest are no surprise at all

I'm not threatened by their misinformation, and I'd rather be able to see all veiwpoints - even ones I disagree with - than end up in an echo-chamber.

They're the ones that require an echo-chamber to protect their delusions. Federating with the rest of the sane instances will hurt them more than us.
