Five other people are reading this doc, right? Wrong! The user with a white avatar is actually a button to start a chat! Why does it look like a user and is placed where all other users are, we’ll never know.
But wait, isn’t there a chat button next to Share? No, that’s comments! What’s the difference? Comments are square, while chat bubbles are oval!
Also, if you ever wanted to check how your stocks are doing, there’s a button for that too.
