The Fundamental Mechanism of Distributed Consensus

🔥 5
2 comments

Your group already shares great links — in Discord, Slack, group chats. But that great article from last month? Buried. The thread where someone explained why they disagreed? Gone.

How it works

01

Create a club

Start a club for any group — your ML reading group, your work team, your friends. Set it to private or public. Invite by link.

02

Share links, add your thoughts

Paste a link and Marginalia pulls in the title, description, and preview automatically. Add your commentary — context, critique, why it matters. That's the marginalia.

03

Build a library together

Every link becomes part of a permanent, searchable collection. Browse by domain, author, or date. Find anything your group has ever shared.

Two ways to browse

The feed shows what's new. The library shows what's been collected. Same content, different lens.

Feed

What's new

Chronological. No algorithm, no ranking. New posts appear in real time. Open the app, see what your group shared today.

The links channel, elevated

Links pasted into Discord or Slack, buried within hours

Every link is permanent, searchable, and part of a growing collection

Reddit karma turning conversations into performance

No voting, no ranking. The quality comes from who's in the room

Algorithmic feeds deciding what you see

Chronological. Everything your group shares, in order

Scattered across five platforms with no shared context

One place for each group. Each with its own library.

Clubs for everything you read

Same tool, different configurations.

M

ML Reading Group

Private · 14 members · All can post

A group of practitioners sharing papers, tools, and experiments. The library has 6 months of curated ML resources searchable by topic.

P

Polyglot Engineering

Private · 8 members · Invite by owner

A work team sharing deep dives on their tech stack. New hires browse the library to get up to speed on past architectural decisions.

T

The Regulars

Private · 6 members · All can post

A friend group sharing local news, restaurant finds, and the occasional meme. Low-key, but searchable when someone asks 'where was that taco place?'

L

Links & Thoughts

Public · Owner posts only

A personal linkblog. One person curates, anyone can read and comment. Subscribers follow via RSS. A quieter alternative to tweeting into the void.

What we don't do

No algorithms

Chronological or nothing.

No karma

Your words stand on their own.

No ads

You are not the product.

No discovery

You find clubs through people.

No engagement tricks

No streaks, no badges, no dark patterns.

No data lock-in

Export everything, anytime.
