A static site is often enough for documentation, notes, and a personal homepage. There is no database to maintain, no runtime to patch every week, and the result can be hosted by any basic web server.

Useful defaults

A small site still benefits from an about page, a feed, a sitemap, and meaningful error pages. These features make it easier to navigate and easier to understand for both people and search engines.

Keep content separate from presentation

Markdown files are portable and easy to edit. If the site generator changes later, the content can usually be moved without a complicated export process.

The main advantage is not fashion or framework choice. It is having a site that can be rebuilt elsewhere in a few minutes and otherwise left alone.
