Since then, I had moved to my own domain as I realized most people are asked/forced to signup and sometimes have to "pay to read". I do make sure I do not tick that monetize button/checkbox or have never agreed to be a paid editor. I even changed my username and I continue to pay for Medium to support other editors (and of course, read their stories).
I like Ghost but aren't they doing lot of things and blogging is not the main/default thing anymore? On that note, if you want to quickly try out Ghost, I have been happy with pikapods.com (I have no relationship with them). I start with them, if things go north, perhaps figure out dedicated resources.
