The way you communicate with a keyboard says a lot about you. If nothing else, it tells the reader whether or not you are attentive to details. Clear communication is critical to understanding people. It's a rare post of mine that I don't re-open and edit at least once, and sometimes multiple times. (I just added the last sentence in my second edit...)
I'm fond of saying "If you can't communicate what you know clearly, then what you know doesn't matter." The reason is that if you can't communicate what you know, it dies with you and can't be shared with others who can use it and carry it forward.
I understand that many people are very good musicians but lousy communicators. IMO that's a regrettable bug, not a feature.
