I make no effort to distinguish writings as autistic or neurotypcial sourced. No, I probably couldn't tell one from the other if I tried.
Something I do pay attention to is the wide varieties of writing styles used. I tack these styles to individual people, not categories of people. Some adhere strictly to proper grammar and spelling; some make no effort to do so; which is more autistic or neurotypical? Some are very terse; some are hyperverbose; which is more autistic or neurotypical?
I prefer to use proper grammar, with license taken for conscious personal style modifications; I know others who choose not to pay much heed to grammar, and who seem at least as autistic as I am. I can't spell myself out of a paper bag (I do try to use a spellchecker); I know others who can and do spot every spelling mistake I make, and they seem at least as autistic as I am. I'm hyperverbose; I've gotten numerous complains of my posts being too long and rambly; I know people who rarely post more than a sentence at a time, and I consider them to be at least as autistic as I am.
For the record, this particular post is perfectly neurotypical; I am feeling very unautistic today.
Good fortune,
