It's all about the number of followers and perceived votes an author normally gets. Have you noticed some authors get a ton of upvotes even when posting a picture of a wall? Or some users that are constantly on the trending page...but don't have any worthwhile content. One that comes to mind is a real estate website or something....I can't imagine people really give a shit about that kind of content here to the point where it's worth over $1k per post.
