If you don’t feel like going through the hassle of setting up a static site generator and finding a place to host it, then you can resort to blogging platforms.
It is a light platform with minimum style that gives you free hosting, free subdomain, free themes and only requires Markdown knowledge to get started blogging.
For a small fee you will be able to use a custom domain and upload images to your posts. With a custom domain and a backup of all your posts, you can ensure your blog wouldn’t go anywhere if the owner of the platform goes rogue. Although that is very unlikely.
Check out the official documentation.
I’m currently using the paid version to host my occasional writing and am very happy with it. It’s not perfect, but what is?
One thing I like about it is that it’s not just a blogging platform, but it’s own little slice of the web. The home page is a list of blog entries from all the blogs sorted by some combination of “toasts” (likes) and age. (And the trending algorithm is both simple and publicly viewable.) I don’t explicitly subscribe to anyone else’s blog, but enjoy just browsing “trending” and “recent”.
