How would you like to make fewer spelling and grammar mistakes and avoid being called out by the grammar police?
Have you ever written that you consider to be a reasonably good blog post or article only to get your first piece of feedback by a well meaning person reminding you politely that actually you made several mistakes. Trust me I’ve been there. It is especially common when you write on a controversial topic or the more popular you are.
If people want to criticize your argument (and can’t) or what to try to bring you down, spelling and grammar are easy points. I’m not saying they aren’t important, but dismissing someone entirely because of a missed keystroke or using “there” when it clearly should be “their” is not fair. If someone’s argument is good or bad, it should be judged on its merits alone, not on their style guide. Of course, if it is impossible or difficult to understand the point being made, that is a different matter altogether.
