I was not necessarily talking about proper sentence construction. I'm talking about shortening words by 2-4 letters to the point that unless you know what is meant, it is unreadable, as if that is saving any amount of time that is noteworthy.
It's not just about saving time, it's about saving money and getting text messages out more quickly Text messages also have a maximum length.
If you text, you learn the language and you know what it means.
It's a natural and appropriate adjustment of language to adapt to the technology. The people who use the technology regularly know exactly what the text words and acronyms mean.
Sounds like those teenagers are pretty smart to me.
