I agree that it would seem annoying, and what you've mentioned is intriguing though. Maybe they thought it could be a window for people to actively help in making posts more visible, as opposed to posts/(post types) visible by nature becoming less visible due to user feedback or behavior. But I wonder how big of a risk it would be to promote any and all types of posts from friends? I certainly wouldn't want someone to promote my sharing of an article about a brand, making me look like I'm endorsing it. Weird.
