Your own blog first if not for any other reason then the fact that you own it and are not at anyone's whims but your own. I used it as an excuse to get Ghost up and running in my Kubernetes cluster. Win-win. Then push content out to Medium, dev.to, Twitter, etc if you're looking for more of an audience.
