Well, I think some set of people don’t get to cross check what they have written which is normal but I’m sure that when someone knows that he or she is writing something that makes sense, the person will want to read his work over and over again…
And other people will want to read it. That’s why the topic and cover photo of a post is really important
It isn't just about editing for grammar - it is about reading it to see if it is interesting at all. Some people are more boring than reading the shopping list of an elderly person.
