Yes. I tend to come back to my posts the next day, see obvious mistakes that could actually change the entire tone of my post and do a quick correction. I know on a couple occasions in my sleep deprived stupor I have just pushed a whole bunch of buttons on my phone that seemed right, but we're were totally wrong.

I try not to be the grammar police unless someone else is trying to be a jerk about someone else's mistake, I just believe it's different when you are putting out official correspondence. You should always be willing to step away and come back to it before hitting the "send" button, in my opinion anyway.

It's a part of being professional too.

There is also the example of autocorrect making mistakes that I otherwise would not have made in the absence of it, and I just exemplified the importance of coming back to it because the opposite mistake happened in this very post, go figure.
