Project mention: I wrote a screenplay for a programming language introduction | news.ycombinator.com | 2025-02-06
Origami is a really elegant utility with a lot of interesting ideas. It still feels like a tool for a more technical audience—maybe it would be good for AI agent orchestration? The stated audience of non-developers who know HTML and CSS and want a code-oriented SSG [0] is simply non-existent. I know Jan is working on marketing, so I strongly encourage him to define a more realistic user profile/ICP which based on talking to real people.
[0] "Origami is designed for you: someone who wants to make a site for yourself or a small organization, who can HTML and CSS, who’s not a professional developer — or is, but wants to build sites more quickly." - -
