as an early gemini convert this is one of the reasons I wish solderpunk would split the gemini protocol and text/gemini mimetype specs. gemini can serve more than text/gemini (e.g. markdown as you suggest), so embedding the text/gemini mimetype into the protocol spec seems rather like embedding the html spec into the http one
I agree in part, and disagree in part. I like that gemini has a "native" markup format, and that its simple and bare-bones as it is. It's a communications baseline, and other things are negotiable between client and browser?
