I don't mind when I am corrected, and yeah, I am a grammar Nazi and correct others.

Having said that, you can correct others in a respectful manner, or a disrespectful one. I try my best to be respectful when I am correcting others but will admit to being human and having reacted to the way in which the person I am correcting has posted (if they are being jerks, I may well be a jerk back). My preferred method is to parrot back what they have said in a way that is corrected, in hopes that they will pick it up and in hopes that it doesn't come across as an arrogant lob across their bow... but, in todays world, I am unsure anymore how to do anything that won't hurt someones feelings.

Why? How do we correct each others? How do we improve our skills in language if we allow others to use poor, and usually very ambiguous language? If we do, we are just undercutting our own language and creating situations in which people will misinterpret what is being said, and increase friction. Worse, we live in a world in which it is rather difficult to misspell something with out the medium telling us we spelled things wrong (or auto-incorrecting us to death). I have a word in red right now, because it's spelled the way I wish it to be spelled, is a non-standard word/construct but is, I hope, the correct construct for same. The interface is giving me guidance as to how to do it right. My confidence is high enough that I have reviewed said word and am leaving it for... my reasons. THAT I can put up with and don't mind and I hope that when the language is used in this fashion, it elevates clarity, versus creating more obfuscation.

We need to accept more guidance from our peers. We need to be respectful when providing said guidance, but we mustn't stop. If we do, we just allow society, in general, to go in a direction without our input stating we'd wish it were heading in a way we prefer. We may be overruled by the greater numbers of society, and we have to accept that, but society has to accept our input or it loses the nudges and may well hare off in a direction most of us don't like... look at the current political situation in which too much of society (I hope) didn't put in their 'nudge' on the appointed day.

If someone points out a real mistake I have made, I appreciate it. Yes, I do correct others if the error is egregious or if it can lead to misinterpretation.

I correct other peoples spelling all of the time. Sometimes it goes unmentioned, other times not so much. The latter are times of some entertainment.

I might PM someone if it really changes the meaning of what they are trying to say. Mostly I edit it in my mind

Depends on the information they're sending. If it's important or from a business then it's annoying and seems unprofessional it discredits businesses for me
If it's from a friend not a big deal just so I get the jist of what they're saying. Sometimes you're in a hurry or typing from a phone and speech to text screws up. No big deal.
It used to annoy me but then I realized it is on them, has nothing to do with me and not worth the mental energy to correct them. I'm not an editor

Maybe because I edit books part-time for a publisher....but typos, grammatical errors, and incorrect punctuation drive me crazy and jump out at me like a pink poppy in a field of red roses.

Interchanging homonyms or homophones incorrectly is so common now...I don't see how people haven't taken the time to learn the differences such as "there, their, and they're" so as not to make these juvenile errors.

But, the very worst thing....those people who type is some sort of lazy text short-hand: U instead of You, ur instead of You're/Your, 4 instead of for, etc.

There are a few things that bother me in this area, spelling errors and punctuations problems don't worry me as I am dyslexic myself but when people write what they speak there are problems that creep in that drive me nuts, probably because I have been dealing with this condition my entire life.

What I can't handle - let's be pacific or pacifically <--!!!! GRRRRRR
The change was implementated to bring about <--- GRRRR

Things like that drive me nuts, so they are going to be an ocean?

Minor mistakes where the meaning is still clear, no problem. I may ask further if the meaning is garbled, but appears to be jerk based.

Its called Anal Fixation. I was in Graduate School and was attempting to write my thesis on 'Altruistic vs. Competitive' Education which to a Psychology Professor is putting a dampening light onto his future and mine also. I threw myself into ring and researched thoroughly, documented every reliable source and footnoted each and every source and then had to type it myself which can be a problem when you are performing all of the above. It was the very late 70's and computers and spell checking was into a brain tank and not where to accommodating.
Bottom Line I get the paper back as a B+ with the connotations that it 'was a very thoroughly researched paper faulted by many grammatical and spelling errors.
To me I fully understood the correct Degree Academic Degree Stature of Importance and Recognition which is that a B.S. Degree is to be understood as Bull Sheet. Further recognition is a an M.S which included More Sheet that leads into a Ph.D which is being awarded with Waders because you Piled High and Deep.

I am a grammar nazi. I correct novels, even.

However since it's the internet, and my hands are clumsy and I can't type well, i let it slide more

If someone who is really annoying and petty uses poor grammar, I'll comment to annoy them too. If someone makes a point of pointing out others' minor mistakes, I kind of enjoy pointing theirs out.

I feel a lot better about myself since I stopped judging others for that kind of thing.

The mistakes of others matter if they're committed by my kid, student, or employee. Since I have none of those...

If I make a legitimate mistake (i.e. not a typo or text-speak) I would be somewhat surprised and very much appreciate knowing about it.

I don't correct, but I do tend to judge. Then I look at my writing sometimes and wonder what people must be thinking about me. All typos, of course.

Unless it's an error in a headline, I generally don't correct. People make typographical errors all the time. I don't find it a big deal unless it's something that should already have been edited by a second set of eyes or unless it's so full of errors that it's incoherent.

I cringe any time I see this. However, I only correct my own children. Sometimes they`ll do an obvious one just to troll me!

I don't feel more than an occasional twinge of need to be controlling around that. I've been on social media long enough to know that many people use uncorrected voice recognition, mobile device virtual keyboards, etc., or English is a (sometimes distant) 2nd language to them, etc. Also, even some people with a decent ability to type and a reasonable command of grammar, aren't very good at putting coherent thoughts together. They're more verbal and writing isn't their thing. Some aspects of modern and online slang and "leet speak" don't help.

Then there's the whole problem that some people just can't read past your first sentence to save their own lives. That seems to be more of a problem with email business correspondence than it is in this format but sometimes you can tell someone hasn't actually read what you wrote, from their reply.

I try not to judge all this, as it would make being online a lot less fun to do so.

I can generally tell when someone has simply made a typo (or maybe dictated the post) and when a person actually doesn't know what a word means or how to spell it. the latter bothers me and since i am an ex-english teacher and still a writer, i might or might not resist the temptation to correct it. i admit that i am more likely to correct someone with whom i disagree than someone with whom i agree. that's probably wrong. too bad. sometimes someone will come back at me with a criticism of my lack of initial caps. well, i have arthritis in (among other places) my hands, and while i make initial caps in formal writing, i do not consider social media posting to be formal writing.

A lot of times it does bother me, sometimes I just laugh. I refrain from correcting others. I tell myself they’re just typos.

My attitude is it's just texting I just ignore people when they get real OCD on things like that that's kind of their little personal demon

Not enough to give it any thought I just pass it by.

I struggle with that one.
When I see mistakes, especially common ones, it's all I can do to not point them out.
My intent is never to hurt anyone's feelings (unless I think you're being a dick-in which case, I'll use that against you-I don't always take the high road), but to help.

I've had my mistakes pointed out to me, and I appreciated it. I used to write "alright", but that is wrong, the correct way is "all right".
When it was pointed out to me, I stopped doing it.

Might tell someone to use their spell checker. Will gladly correct a troll.

I do not correct others. And while I appreciate being corrected if I've asked for proof-reading, in normal circumstances, a "more knowledgeable than thou" correction just shows me that the reader is not gracious or bright enough to understand my meaning with a word spelled incorrectly. It also tells me that I would likely not enjoy being their friend in real life.

That said, if I answer a poorly spelled question, I will spell my reply correctly - and don't mind if people do the same with me - and I will quietly check who is right and edit my work accordingly. This method is more diplomatic than public shaming of the writer, who might be tired, dyslexic, have poor eyesight, etc.

Someone corrected me here on this site, and I believed I thanked them, but stubbornly left the mistake intact as it was in my post... even though I usually correct my own posts with the edit feature right way if I notice an error. I'm a stickler for grammar and spelling myself, but try to give some grace to others - and desire the same.

It's silly. If you understand why bother, don't need to feel like im in school again

It doesn't bother me that much. I'm not the greatest at spelling and Grammer. I take it as a learning experience. When I'm reading someone else and I come across spelling and grammatical errors I just substitute the correction in my mind and keep reading.
