Whats the point?
I really cant see any use for an obscure language pack like this. Any useful work (websites,email,whatever productivity needs to be done) will need to be in a common language that the masses can read, unless you want to limit your audience to a few thousand indians. I presume all cherokee can speak english anyway, so really, whats the point?
Welsh is the same, its a dead, pretty useless language thats only survived this long because the welsh govt have forced it on kids at school. It serves no purpose beyond academic curiosity in the 21st century, as evidenced by all the english words the welsh need to use for modern items/concepts.
I used to suffer s4c before freesat liberated my telly, and the ridiculousness of it was evident in interviews where the presenter sometimes asked questions in welsh, and got a reply in english. So why not just use bloody english in the first place?
As an aside, there was a survey done by a tv ratings company a while back and they estimated that quite a few welsh language programs on s4c didnt receive a single viewer. I imagine cornish programming on bbc alba is much the same.
As a poster above said, document these dead languages, archive them, then let them die. Certainly dont prop them up with govt funding and forced learning at school.
