Own your work
The underlying truth behind all such discussions is that too many people focus on the mechanics of content hosting and delivery but have nothing special to actually share. So they will spend all their time engineering the perfect blog site from scratch or moving from platform to platform looking for an ideological fit while no one really cares about consuming any of their output.My advice is always to forget about the details and just write. Set up a medium account, or substack, or blogspot, or get a VPS and install Wordpress or Ghost, or just tweet out your article line by line. If there is value in what you write then the readers will be there. And they will follow you if you decide to move your work elsewhere in the future.
