Are there many people who go to medium directly? I've only ever gone there because someone's linked to a post here or on Reddit. Which is something you could do for your own blog's post.
But seems like that recently has changed. Now the paywall-ed articles are shown more to people[1]. So even authors with large number of followers don't get their articles shown to their followers.

I think if you write good content, and post it on good programming communities like HN or Reddit, I don't think its that hard to get it noticed.
