The whole point of writing anything is to communicate an idea. This idea can be big or small; simple or complex, but often it's how we communicate this idea that impacts how people respond to it.
A common issue that I see people work through when writing is their need to write in a way that engages their audience. Give them the ability to communicate face to face, and they could explain all day the merits and strengths of their area of expertise. But put a keyboard or a pen between them and their audience, and they lock up. After all, writing has all these conventions and rules that we know exist but never really learned what those rules were, and talking about it is just so much easier.
It may come as a surprise, but you can do both.
