And you can watch all this happen in the "Network" tab of dev tools when you load this page: bluenotes.social/community-no...

You'll see calls to the app.bsky.feed.getFeed (the Bluesky app view), which returns posts with the 'annotation' label, then calls to org.opencommunitynotes.getProposals

Oh and a tip. Frontends should pass the DID of the Bluenotes labeler in the 'Atproto-accept-labelers' header when making calls to the Bluesky app view. This way, users don't have to describe to the labeler.

And one small detail I forgot in the above: when you call the `getProposals` endpoint on a post that has the `annotation` tag, add `&status=rated_helpful` to get the note that was actually rated helpful (in case there are other proposed notes that weren't rated helpful).

Once a note reaches "rated helpful" status, the proposed label becomes an actual label emitted by the labeler. But since labels can't include the note text (yet), frontends need to fetch the note text from the original proposal.

The endpoint is getProposals, instead of getNotes, because when somebody submits a note, it always starts as a "proposal" record, from the social.pmsky.proposal schema.

Example:

2. Next, since the annotation labeler doesn't include the actual text of the note, you need to call the getProposals xrpc endpoint from the community notes service API.

curl --get 'https://api.bluenotes.social/xrpc/org.opencommunitynotes.getProposals?uris={URI_OF_ANNOTATED_POST}'

Yes! I should write a blog post about this. But first, very briefly:

1. First: posts with attached Community Notes will be issued a 'annotation' label from the Bluenotes Labeler: bluenotes.social/profile/blue...

Bluenotes Community Notes Labeler (@bluenotes-labeler.bsky.social)

The Community Notes labeler. Labels posts that have notes created by Community Notes users on https://bluenotes.social

Thank you to whoever added a community note to this post!

jonathanwarden.com @jonathanwarden.com · 1d

Hahah yes. I probably should come up with a better logo. Just haven't thought of one yet.

On the other hand, maybe I'll send up getting a lot of people using my app because they think it's Bluesky for musicians ;)

X adds an additional "Rater Impact Score", which I haven't yet implemented. Your rater impact is how many notes which you rate as helpful (or not helpful) that ultimately reach "rated helpful" (or "rated not helpful") status. You need a rater impact score of 5 before you can write notes.

The Matrix Factorization algorithm Community Notes uses kind of has a built-in reputation system. Most people don't see it that way, but the fact is that if you consistently rate notes as helpful that ultimately reach helpful status, your future ratings will effectively have more weight.

Oh thanks for testing that @zicklag.dev . I should mention the app password option in the beta guide.

@erlend.sh other than an app password there's no workaround. I was just going to make a list of people who were waiting for OAuth so I could notify them when it was ready.

@cnviolations.bsky.social Thought you might like to know, I've implemented the Community Notes feature in a fork of the main Bluesky app. The Phase 1 beta is live at bluenotes.social.

I've built Bluenotes, a fork of the Bluesky app with Community Notes. Phase 1 beta is live.

bluenotes.social

Looking for thoughtful early testers. The algorithm needs data from diverse perspectives before it can identify helpful notes, so we're building that foundation first.

Interesting writeup, i think one idea that is sort of similar to the UUID approach would be just using Tags to create ad hoc community spaces without central authority. Posting a record with #Seattle (ideally not inline with the text) creates a sort of community space in the indexing of the tags

Yes I call it "hate following" when people follow someone just to dunk on them. And it's often "behind their back", where they post a screenshot to Twitter or Reddit.

People’s perception of a problem are often have little relation to the reality. But how do you evaluate reality? Certainly not with trends. If something is a problem it’s a problem, whether it is getting better or worse.

One experiment I'd like to do is run the Community Notes algorithm on some Polis conversations, and vice versa, and see if they provide similar insights on group opinion.

jonathanwarden.com @jonathanwarden.com · May 1

Hi, I'm very interested in this stuff! I've been doing some experiments with dimension reduction on community notes data and data from some of the deliberative experiments in the deliberative democracy world. Also working with metagov.

Sorry I couldn't make yesterday's call. How did it go?
