On the rare occasions that I do publish, I use my laptop with Grammarly, (And still make mistakes) but Medium has removed the ability to edit comments with my smartphone, so I make a lot of embarrassing mistakes when replying to an article. (I didn't develop texting skills, so I poke with my index finger)
I agree with you 100% though. Even typos in a story's title won't discourage me from reading it, especially if I already admire the author.
