20 links is 4 links a day for 5 days a week, not quite a full time job.
It is more work that most people want to do.
I know somebody who was using Medium who was really impressed that he got 70 views on something he wroter. I found it hard to break it to him that I would have been impressed if I'd gotten got 70,000 views on a blog post -- and that's the difference between the easy way and the hard way.
IMO a more effective way is to offer users a chance to post links on their social network. If they are satisfied, the chances of others liking the position will be much higher. Once I got 22,000 views on a post without any effort (this hasn't happened another time).
