I think it mostly catches newer people who aren’t sure where to go or how federation works. Originally I went with .ee only because it was at the top of the list I was looking at and for some reason .world has always rubbed me wrong.
Alas, ee was home to a lot of “conservatives,” so I just picked the most generic sounding one after getting banned for my radical left ideas! “Discuss.social” is very boring sounding haha.
Although, I do like the use of the .social tld, as I am a fan of relevant tld choices.
.ml is for Mali, in west Africa. And .ee is for Estonia.
