What are mostly unknown domains that are quite good?

[Grant]

We're seeing many kinds of domain extensions these days. From the likes of .io .to, and a few others, it made me wonder about unknown domain extensions, and if there are any worth using? Like, could I get a domain that was like .bo or .do or whatever else I want?

I like xyz, I have a site using this extension. This domain extension can be appropriate for all kinds of sites. sadly, a lot of people started using xyz for illegal activities and spam activities and this domain extension is no longer trusted. I also like club, it is good for communities, I have one site using this domain.

I've always wondered why they're isn't a .tex extension, considering how proud Texans are. . Well, is there one like that?
