I just don't care most of the time, lol. I am a horrid typist, and unless the post is littered with mistakes, I can let it be unless I have a major point to make. I spend enough time at work worrying about my grasp of the English language, ain't gonna worry too much on a forum!
My dad sits there (He's mod of a fairly large forum) and types a message. He'll click preview, then not scan, but read the message and then submit. He will shout at me "Does this sound right?" (No, it's not just graofftopicr!).
He's never made a single typo/error (I swear he hasn't lol), and gets really annoyed if he has - "beep" he says the other day whilst looking through an email he sent maybe 2 months ago, "I missed an l out on *woteva word*".
I usually try to get the words spelled correctly. Come on people... it's called dictionary.com and it's free. There are a couple different issues about spelling:
1) If you can't be bothered to spell a word correctly... why bother to post?
2) It takes all of two seconds to proof/edit what you posted.
3) It helps to make your point more concise. You end up looking silly if your working hard to prove your point or explain your position but you can't spell basic words correctly.
4) I find it hilarious that people are on continuously about the discipline one needs to have in order to grasp/study/master a martial art... but they can't be arsed to spell correctly. They're all so mystical or tough until it comes to spelling. LOL!
5) Spelling inccorrectly remarks are often pulled when one person is in a heated arguement with another and needs to shore up they're arguement by diverting the attention to the other persons spelling.
6) Sometimes the whole 'spelling errors' strategy backfires and then individuals make it even worse by taking the 'Nationalist' or 'static language' stance. Of course, they just end up looking foolish.
At the end of the day or sentence, the odd spelling mistake or graofftopicr mistake isn't going to kill anyone. But if your on an internet forum where you lack the ability for facial expressions and body language to help convey points... why would you also give up spelling correctly?! Seems more like it comes down to being lazy. Were not looking for exam quality writing but some of the mistakes are so over the top... it makes you wonder how they get by in the rest of their lives.
That being said though... I still laugh everytime someone types:
