Unfortunately, I don't think the program pays for external views you get from posting a link to your own articles. But is someone else posts a link to your article, you'll get reimbursement. You can help other people by posting a link to one of their articles though. I don't understand why they don't pay for sending external views to your own article. Doesn't make sense. But as someone pointed out on Medium, people clicking on your friend links are temporarily using your membership, which makes you ineligable for payment.
