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.
