“Gemini is a new, collaboratively designed internet protocol, which explores the space inbetween gopher and the web, striving to address (perceived) limitations of one while avoiding the (undeniable) pitfalls of the other.”

I think it has a lot of potential and I enjoyed reading the spec. The project website is here: https://gemini.circumlunar.space/

I wrote the first PHP implementation of Gemini, you can read about that at Gemini-PHP

I run a gemini server at gemini://glasgow.social
