I despise it. Proper grammar and spelling is important. I won't even answer questions with intentional misspelling and shortcut words.
I hate them. I think it makes people sound ridiculous. And of course that lead into people typing/texting, ect. Lyk dis. It annoys me so much can't even explain it. Especially because its younger kids doing it as well, like 12, 13. At least the older ones kind of know how to spell stuff properly and can when they need to. We're going to end up with a generation of (actual and emotional, but that's another thing altogether) idiots.
I don't care much for it at all but I guess it's the newest generation thing. I don't text much at all and even when I do, I still use proper spelling if I can. Guess it's something we'll just have to learn to live with. Not everyone uses language like that but many of the younger ones do so it's going to be an ongoing thing.
