It's easy to get a blog going with either GitHub or GitLab plus their "Pages" hosting environment, or Netlify.
Here's how you can do this with just GitHub Pages or GitLab Pages:
* https://pages.github.com/
* https://docs.gitlab.com/ce/user/project/pages/
Here's how I originally hosted my blog with Gitlab Pages using Hugo (a static site generator):

and then ended up migrating to Netlify when I upgraded Hugo to a new version to support a different theme (Netlify has additional benefits, like automatic live previews):

And here's someone else's 1-hour walk-through of the same workflow:

It's pretty straight-forward process regardless of which approach you take. I hope this helps you get started with your own blog!
No pressure, I’m just looking forward to it.
