Yes, especially mine. If I have a typo, forget a period or forget to capitalize the letter at the beginning of the sentence, I freak out and have to edit it. I don't really mind others' as long as it's readable, but if they substitute too many letters for words (ex. you = u, are = r) and they start shortening a bunch if their words to save 30 seconds of time (like = lyk, how = hw [I've actually seen this], listen = lisn) I put my foot down. It's just lazy to me. And excessive uses if exclamation points and question marks are really annoying. You only need one!
Depends. When I talk to people I usually write ''u'' instead of ''you'' etc. but yeah I'd be better if I'd use only real grammar. I mostly type in real grammar if I'm anwsering any questions on here & stuff.
I always tend to care for proper grammar, no matter if it's here or on any other site. Mainly because bad grammar is something that gives me extreme headaches.
Sort of because I think it's dumb to misspell simple words and I know how to spell. If you care about what some people think on here you shouldn't type like this on here:" How r u doinq 2day?" I don't like when people use q's where g's should be...
