That is the question!
Of course, NOT! -this is the opinion of many educators and parents , concerned about the risk of possible alteration of communication skills .
Well, dear language lovers, do you really think your opposition counts?
The language- any language- is a vivid asset of humanity, so it will evolve in spite the will of the ”pure language” defenders.
Every time a new language trend appeares, there are people that criticize and reject that, blaming the others that adhere to the new ideas and naming ”barbarism” any new insertion into the world of communication. And this is one of the reasons of the distance between different generations, if you ask me.
Just think. All the kids use the new language. They need to communicate fast, because they are texting during their walk, during traveling by bus, during classes, during homework- and most of the time they have at least two persons at once engaged into this sort of conversations . They must solve everything fast!
And I have news for you: the corporatists found very fast the advantages of this system and they use it !
Now, my dear responsibe adults... let's make two lists about the use of internet language :
1) threads :
-the alteration of "normal" communication skills (possible but not compulsory);
2) strenghts:
-facilitation of faster operational communication;
-improvement of eemotional expression of ideas in written communication (we LOOOVE emoticons, don't we?...);
-forcing your kids (your own kids or your pupils) to give up at internet language would push them either to use it anyway and to have a permanent conflict with you , or to be seen by their peers as "that weird kid"

Well, what do you think? Is it or is it not useful for you to start using this language? Today, tomorrow? Yes, No, Maybe?
