Sometimes we communicate through words, sometimes not. When we do use them, we could write, or communicate orally. Both are good, and suit certain occasions well. I recently joined Instagram, for instance, where the emphasis is on the visual, and text is incidental, or by the way.
Facebook, where I have been longer, has an equal emphasis on both the text and visuals. I do a lot of text, having been into writing, so I am quite comfortable with fb.
About communication, public speaking is an art that can help in certain professions. If you are a politician, persuasive communication can win you votes. If a spiritual Guru, followers. If a teacher, maybe students who are fans.. or become fans. Of course, there's more to teaching, but communication is a very important part.
Of course, we make statements through how we dress (up or down, as students tend to do), act, or behave in a place where others are present- at a party, or other public places such as airports or when walking in a park.
Important to understand various facets of communication, both as a receiver and sender.
