Based upon my personal experience this point rings very true. I had a piece that Medium tweeted and posted on their main page as a featured article. It’s still getting a few reads a day more than a week later. But I’ve seen only a slight increase in traffic on my subsequent posts in spite of the fact my one big hit increased my followers seven fold. Stuff I put behind the paywall gets practically no attention at all. Granted, I had very few followers to begin with, but I would think there should be some noticeable improvement in views, if not reads, after going from 10 followers 2 or 3 weeks into my Medium experience to just over 70. When I read that one poet received 100 dollars for work he published on Medium that received just one clap, I knew it was time to give up trying to make sense of this. Medium does contain some very interesting and worthwhile content, though, and it keeps me writing. That’s not nothing. I’m just not sure it will ever get writers noticed. Time will tell.
