Markdown Browser

Goal

Build a very simple web browser whose native document format is Markdown.

This is not a Markdown editor inside a conventional web app.

It is a browser for a simpler web.

What trigger can do

Written 8/4/26 for Jake Savin and Dave Winer. Describes trigger v0.5.0 running usertalk v0.3.0 at https://trigger.usertalk.org, backed by a SQL copy of Dave's Frontier object database — 212,591 objects, decoded from the real .root files.

The one-paragraph version

Trigger is a web server that runs UserTalk. You send it a script over HTTP and it answers with the value. The scripts are Dave's own — not ported, not rewritten — read straight out of a decoded copy of his object database, and the language underneath is a fresh implementation of the UserTalk interpreter in JavaScript. As of today it runs the nodeEditor build pipeline end to end: an outline written in Electric Drummer on a laptop is uploaded, built by nodeEditorSuite.uploadScripts, and the rendered files land on a live website.

Universal Mentions

Universal Mentions is a simple convention for mentioning people on the open web without needing a central username system.

On Twitter/X, Bluesky, Mastodon, and similar systems, a mention is usually something like:

@davewiner

That only works because each platform controls its own user directory. On the open web, there is no single global directory of usernames.

	const prompt = "Build a short, balanced reference page about " + name + ". "

Superman

Superman is a fictional superhero appearing in comic books published by DC Comics. The character was created by writer Jerry Siegel and artist Joe Shuster, debuting in "Action Comics" #1 in June 1938. Known as a cultural icon, Superman is often hailed as the archetype of the superhero trope and has had a profound impact on American culture and beyond.

Creation and Development

Superman was conceived during the Great Depression, initially as a villain in a short story and later reimagined as a hero. Siegel and Shuster sold the character to Detective Comics, Inc., which later became DC Comics, kickstarting what is considered the Golden Age of Comic Books.
