Or your own blog. Though, honestly, for very occasional stuff, Medium probably makes more sense.
Pardon the interruption, a free static page hosting would respect the reader a little bit more than Medium.
Personally I would (do) go with a free hosted service like Blogger which will handle big traffic spikes. But if someone is just wanting to push out a blog post or two a year, I'd be hard put to argue against Medium.
If you're looking to write coding related content - I recommend dev.to as well! It has a lot of the same benefits as medium (built in readership), without all the popups, etc :)
You should give it a shot
Thanks for the encouragement. And the great article.
