I agree. However sometimes it's good to do tiny side projects in a language. This allows you to learn, see if it's really nice, help the language and its ecosystem to develop and become stable.

For use outside of production it seems okay. There are two Sinatra/Flask/Express style web frameworks (Nickel and Iron), a browser engine (Servo), a game engine (Piston) actively developed. So if you have interest in any of those or interest in implementing something like that you might be able to make your project shine. Also really nice on your portfolio if you ever want to get a job where Rust is already in use.

Or one just has fun with it. :D

Agreed. I would do a small project just for fun.
