With the USA population and the Internet presence of the USA citizens, you would expect at least one large generalist instance based in the USA, but it doesn't seem to be the case.
Any ideas what the reasons might be? Is this just a coincidence?
Edit: for Lemmy.world:
The website and the agreement will be governed by and construed per the laws of the following countries and/or states:
I did not know that .world was made by a Dutch person. Thanks for teaching me something new.
.world seems to have been the default instance people went to when they left reddit. It's more or less than mentality imported into Lemmy. This led to the fact that creating a US specific instance is not necessary. .world fills that niche enough.
If Lemmy and other fediverse discussion areas had developed slower and more naturally there might have been more of a country/instance symmetry, but anyone who was around when the Reddit implosion and migration happened knows that it was total chaos and a grab bag of where a new user should sign up. Lemmy and the rest were not ready for such a shift, and now that everyone's been in a place or two for a while, short of a closure or blocking or whatever there's no reason to move around to a matching country and instance, if there even is one. People mainly look for popularity, activity, themes, and engagement, and if that's found on the other side of the globe it works.
Probably trying to mirror Reddit, which had /r/politics for US, and /r/worldnews for everything else. There was a lot of effort (probably wrongly) to try and copy Reddit over instead of finding new ways to do things. /r/worldpolitics was the original sub, but there's an interesting drama story there.
