Oh, God, do I hate it! It's chipping away at my faith in humanity's collective intelligence. D:<
I hate all forms of it. Shortening words 'cause ur 2 lzy 2 tp da hole msg (especially on something like a forum, where you aren't 'rushed', and for the record I don't text like that either, on the rare occasion I text at all), Capitalizing Every Word In A Sentence (Seriously. Why go through the extra effort to look like a moron?), CAPS LOCK IS CRUISE CONTROL FOR COOL (No, it most certainly isn't), and what makes it all worse is when the one writing it doesn't even know enough about grammar to string it together in a way that can at least be read/deciphered. That && thing pisses me off, too. I can't not think of ditzy myspace *****s when I see it. Who the heck even came up with that and thought it was cool? :/
On the internet, where pretty much most of your impression on people is through typed text, it's not hard for me to assume you're a moron if you can't at least make an effort to make sense.
