A lot of comments making the counter argument "speaking > writing" are smuggling in interactive communication. And in that case I would have to agree, it's faster for most people to talk than write, and going back and forth in conversation is easier than in text. But that doesn't scale. Even if you have the best ideas, you won't get very far coordinating others if you can't communicate non-interactively.
