I remember a refrigerator magnet my mom used to have that read, “They only notice if you don’t do it.” The magnet was about cleaning the house. If the house is clean, no one notices, but if it’s dirty, then it’s painfully obvious to everyone.
That’s what proper grammar, spelling and punctuation in your blog is like, which I wrote about last week. It’s basic and the lack of it will make you lose credibility. But it won’t make your writing more interesting or readable. Creating text that keeps the reader interested is a totally different story altogether.
