You're right, we have to keep up with the new words entering our language. I can't really complain as I'm with English all day every day, but those who are not familiar with the language can encounter a lot of trouble. Slang is a different question though.

I think the news, the informations have to be clear and to use new words, acronyms or words in a different language don't help to be clear.

Exactly! But unfortunately it is not the case.
