But kudos to the effort and the idea of keeping news small is a most noble cause
(Yes I know .us exists but it’s not as common as .com)
If it was newsminimalist.co.uk I don’t think anyone would really complain that it’s UK-specific news, right?
I'd say, .com is just the default. If you go location/topic specific, you go with another TLD.
To the 130 million (domainnamestat.com) domains, registered in the US, there are like 500 million domains, registered somewhere else. I couldn't find any numbers for how many of those are .com and how many aren't, but you cannot just ignore those. Just because most domains registered in the US are .com domains, doesn't make .com a US domain. That's a really egocentric point of view.
