Google's John Mueller said on Twitter that Google doesn't count your typos. He said that it is always good fixing known issues with your site, be it spelling mistakes, technical errors, etc - Google doesn't sit there and count your typos.
He wrote "It's always good to fix known issues with a site, but Google's not going to count your typsos."

I wonder if he wrote that the way he did on purpose or not?
In any event, I can tell you I often publish here with tons of typos and when people point it out to me, it doesn't make me feel good about myself. I am not too worried about my Google rankings when it comes to typos, but it does make me look unprofessional and sloppy. So I care more about what my readers think when I publish typos, versus what Google thinks. Not to make excuses, but this is a free site, I do not have an editor here and I often do not have time to proof each and every post - so I do appreciate all those who send me messages about typos here.
