The Gemini protocol is brutally simple, which makes it just about too useless for apps, tracking, and commercial purposes. Gemtext, the format for Gemini pages, is very basic; with about half as many features as markdown, it’s barely a step above plain text. As a result, Gemini is a small universe of blogs and personal sites.
Its simplicity makes it easy for people to create compatible clients and services for it. It’s self-hosting friendly and there are also hosting services, like smol.pub and some pubnixes.
Of course, you’ll need to get a Gemini browser or visit a Gemini-to-web proxy to access it.
Why not both? There are bridges that automatically convert and serve Gemtext to simple HTML for “regular” browsers.
In a similar manner, I wrote a set of scripts that takes gemtext source and creates both Gemini pages (by adding headers and footers) and static HTML pages (same but with some web-specific niceties - CSS, even JS snippets)
(And yes, I really enjoy gemtext markup for its simplicity)
