If I missspell [sic] a word when typing a comment or post on this website, the word is highlighted in #FFD9D9 (hex color). I usually notice the highlighting and if I'm not sure how to spell the word, yes, I'll look it up.

I'm dyslexic and have brain damage. Sometimes I spell a word so badly even google doesn't know wtf I'm talking about.

Short answer: yes.
Explanation: I really DO make every effort to be to be as accurate as possible, first so I don't get misread, and secondly, so I don't sound like a goof in a discussion ?

1- the purpose of language is to communicate a thought. If the thought is given by one and received by another, the job is complete.
2- i grew up pre-internet and consulted books made from paper if i was uncertain of a word's spelling or definition as well as if i required a synonym. It seems that in this world full of technology where i can literally type a word phoenetically into a search engine and retrieve spelling, meanings, and synonyms, it's irrational that as a whole, socital communication skills have declined.
3- i too make mistakes. I am hardly an expert, and frequently errors occur from my haste in submission, or lack of proofreading.

In short. Yes. In response to all your words, yes!

I am no grammar Nazi, but I do insist that people who expect me to read their posts have enough respect for me to make their prose reasonably comprehensible, coherent and concise, and then to interact in an intellectually honest and epistemologically humble way.

Any living language will evolve. "Linguistic drift". There is no correct English language tho there be correct English grammar. Other wise English would not absorb other languages, slang, colloquialisms, sounds etc. Butchering the language is the evolving of the language. Very irritating. "true 'dat"?

The internet screwed up my spelling. People misspell things just so closely to appear plausible, that for me can rub off.
Apparently I've trouble spelling diarrhea and some other ones that escape me at the moment.

Back in college a girlfriend and I would spend ridiculous amounts of time on the phone discussing spelling and grammar in a way that bordered on "grammar porn". It was a BIG DEAL. ?
Funny that when we would turn in writing assignments I would be the one to make the A, but she went on to get her masters, later showing me parts of dissertations that hurt my head. By comparison I was a very "Betty Crocker" writer, dry like beef jerky, her bits would take you on a journey down a beautiful primrose path to nowhere. LOL I guess mine were just easier to grade - shrugs.

FF some years I became mother to a girl with dyslexic tendencies, and while she can write perspectives that would have put her aspiring writer of a Dad under the table her RL pronounciations & spelling aren't always on point (oops I misspelled something right there) .
This situation has cut the guts out of my grammar nazi tendencies.

But yes, in the feels, I've got to check the googoo once in awhile. Spelling is the least of my worries however, since I'm horribly ADD at times and a pathological skimmer have to check that I've read something correctly & watch that I'm not repeating myself.

I do it quite often but then I don't come from an English speaking background.

Give me 7 cups of coffee then I will read this again.

I am a spelling nerd. One I see a lot is, well, alot. A lot is not one word, and lots of folks spell the plural form of a word, with an apostrophe 's'. Like Monday's. The plural is Mondays. Apostrophe 's' indicates ownership.
