Maybe? I based my conclusion on the experiences of sitting in a room together with other people, but being able to converse with them quicker via instant message on our laptops.

Now that I think more about it, maybe the raw speed is not quicker, but the quantity of ideas conveyed per unit of time is higher due to being able to scroll back and forth in text for the listener, as opposed to wasting time clarifying mumblings or repeating what one said. Especially in a group setting where you do not have to take turns speaking.
