I dunno, sometimes its important. sometimes you gotta correct people. When it's misspellings usually their able to correct that when they need two. lack of punctuation for speedy expression in low formality formats like this, fine - you can fix that if you need to be professional.
But misplaced homonyms, unless someone corrects yew, your gonna be stuck being wrong you're hole life, know spell check will save you, your just ignorantly oblivious too being correct. It irks me I think four being sew representative of a greater collective embrace of ignorance - like sayin I don't half to care, it doesn't really matter, I can function just being dumb, I don't need too bee grammatically correct but Its not cool to not no what your talking about. And its so much worse hear.
like how are you going to talk about brakes, work on brakes, have parts break and not bother ever getting it correct? How are you going to pedal start a bike with new carbon reed petals from treats or another site that peddles moped stuff, and not bother to even care about looking like (or rather BEING) a brainless boorish twit. fix your dumbness!
