I don't think training materials would be necessary. YMMV. Most people get and appreciate the threading model.
Clients could be improved, I guess. Myself, I use a self-improved version of Tass that I originally got with a copy of Coherent (a UNIX Version 7 clone) around 1991. It uses an ncurses 'gui' which I admit I have thought of upgrading from time to time so that it uses a real GUI such as GTK.
However it works well enough, and though I suppose it could do with improving, it works well enough that I can't be bothered spending the time to debug/rewrite it.
My main thrust is that most people have never heard of Usenet and what it is capable of.
