I cannot help myself when I use one of them....
The truth is, I do not think it is appropiate.
Communication is changing but I wouldn´t say that it is "Evolving".
Right now, I can see my kids writting with lots of mistakes...like "Kiero" instead of "quiero" (verb to want) and this all is deforming literature, basically beacause this kids are just writing whatever the sound of a letter tells them, not correctly. I´m a writter so I´m annoyed!!!!!!!!:pLOL
