Thanks for this nice article Paolo! You put into words what I’ve been thinking lately.
4 days ago Roberto, also from Argentina, posted in the forum and I left this as a PD:
Could I answer in spanish, which is my native language? Maybe that’s a question for another post.
While my question is not directly related with your post, it made me ask myself, “What if other people can’t benefit from this answer?” or “Should we have a paralell forum for spanish questions?”. Related article on the Portuguese version of StackOverflow
Obviously, we are a minority so I’m not sure the paralell forum is worth the effort.
I got used to English but, as you said, that’s not the case for everyone.
Last year, I joined an initiative to translate Python docs to Spanish and we made it to the official site. 
Maybe we should try to do the same with Django translation on Transifex, which is not so difficult to use.
This is by no means a compliant to the people around Django docs, I just wanted to share the feeling.
Best regards!
