You are still waiting for your chance to pimp up gemtext, do you?
~bartender? Some more of that home made lemonade, please! Thanks!
WELLLL, since you kind of asked. I am one of those who prefer monospaced font (jetbrains mono semibold) everywhere on screen, unless it's a LaTeX typeset pdf with serif fonts. I am grateful that emacs/elpher can display gemini content in monospaced font. Why? Because it is much more readable to my eyes/brain/pattern recognition chain. And the same argument goes for colors. I cannot discern dark blue on black background, or middle grey letters on light gray background. I might even think "Oh, this looks nice!", but three paragraphs in, my eyes hurt. Sorry. It does not help that I have recently developed an extra problem on one eye. So, low contrast in color, thin or sans serif or oblique fonts, no matter how tastefully arranged, are a burden on my eyesight. So content should be content, and presentation should be entirely under my control, in my not so humble opinion. Gemtext achieves that.
The other thing is this: gemtext is so simple, that I can memorize the few character groups to indicate a headline, quote, link. I have given up on html (or xml for that matter) really quick. I keep everything that I might want to read again, either in plain text, or (you guessed it) in LaTeX, if it needs to look more pretty. However, you can serve .pdf and other formats very simply via gemini:// ... so I don't buy into "gemini/gemtext is not expressive enough". It is. It is just not made to copy the big web in any way --- at least this is how I like to see it.
