I have been running my website at taborsky.cz for more than twenty years now. At the beginning, I hosted everything myself, just because there was no other way. I hand-crafted my HTML, or used PHP for some simple templating to automate it.
As the years progressed, I started using third party services for posting my articles. First Blogger from Google, later Medium. These things were a massive upgrade. I especially liked Medium's simplicity and focus on the content.
