If you look through enough of my posts, you can probably figure out that english is not my primary language. I specifically don't have any spellchecker when I write these posts, so often a bunch of typos slip in. I however, don't care. I skim through my posts before posting them, and if I see something that is obviously wrong then I fix it. However, a misspelling a word like immediately (I just had to google how to spell that) isnt something that I care about. You still easily understand what I mean.
The main reason I don't bother with spellchecking is that seeing a typo in a post is a good way to tell that it wasn't written by an AI. It's a peak into the author, seeing them for the human they really are. I find that nice, a human handshake in the form of a mistake.
