I hate it when I correct somebody on a common spelling error, and they shrug it off, or even get offended, saying, "Nbdy cares its the intrnet!!".
WRONG. I care, and for a damn good reason too. When you type and spell out words incorrectly, haphazardly shooting out these abbreviations that you've gotten so used to, you develop habitual skills in typing out in that particular method of speech. (Though I dread to call such a thing a "skill".) So as you speak that way over the internet more and more, you reinforce the generally accepted method of speaking or spelling that way, both in yourself and others.
This process is how language changes, and simplifying the language you think in simplifies your thinking process'. Lacking flexibility of thought and speech negatively impacts your ability to think and speak, and this process that so many people are encouraging, effects the entire English-Speaking world, and to a lesser capacity (On the internet) other languages, that are equally as beautiful to speak and listen to. Please don't dumb down languages, it's a horrible thing to do.
And to further my point, constantly practicing correct spelling, accepting it personally when other people correct you (Only if they're right, of course, try to double check if you have doubts.) and complicating the sentences, paragraphs, and potential stories you type out, can only make you better at writing, and thinking, in English, or any other language you speak. Garnering experience in typing this way is a valuable skill to have, and it's honestly not that fucking difficult.
There was a point in time when the amount of words commonly used in the English language where quadruple the amount they currently are. People spoke to each other much, much more, and did it well. The places of socializing on the internet could be a chance to redeem the social standard of being well-spoken, if it weren't for the lazy want for typing just that one second quicker. I just really hope that humanity can retain the ability to speak to each other with varied flavours and contexts, rather than devolving into snorts, grunts and "no u"s.
So please, people. Learn to fucking spell, or I will goddamn correct you. WHENEVER, THE FUCK, I WANT.
