It's exactly that sort of silliness that has now become total nonsense. If you're 17, you probably write something like this on Facebook walls:
OMG callll meee 2nite!! i mettt dis gurl n seh sed seh nos u!
I can't stand txt spk. That's text speak for you foggies who can't or won't navigate the dangerous waters of instant messaging technology, where English goes to die. Though, I think the extreme above example is what happens when parents friend their kids and said kids mutilate their words to give their mom a headache when she tries to read her daughter's wall posts.
I'm not terribly opposed to text speak on a cell phone. If you're relaying a quick message, doing it quickly makes sense. Personally, I have to text out everything in full words, complete with punctuation, but that's just me and my anal neurosis. But emails? Really? Facebook? It takes longer to type like a retard goat on drugs than it does to get the job done properly.
But I suppose I grew out of my thanx years. Maybe the teens will grow out of:
ily babyyy <3<3<3 tryy da celll muah!
One can hope.
