Making it easier to find communities you love via ATproto. We're all in the same boat, so let's row together.
The openness of the ATP ecosystem is an amazing quality. Makes it feasible to extend what the Bluesky team built in a hundred ways. They made some very thoughtful design choices :)

Ordinarily bootstrapping a social platform from scratch is fiendishly hard. But with ATP, the content and creators are already here—we just need to do a better job of connecting them to consumers. The cold start problem is mostly solved for us

What’s the A/B?

- Infer topics from posts automatically
- Weight reach by user's influence in a topic, calculated PageRank-style
- Serve conversations as digest with most relevant on top instead of variable-rewards dopamine lottery feed
- Serve suggested topics to join as weekly digest
- Friendlier UX

Working on a better Reddit for ATproto! If anyone’s interested in this problem space hit me up

Interested to hear more—what’s an example of a lexicon you’re imagining here? I suspect ML remains relevant even if it’s exposed to the user via a lexicon.

Happy to chat here or elsewhere, will dm you my cell

I’m sure there are virtual gatherings but don’t know about them personally :)

Hi Maddy - if you care to share, I'm curious to hear a high-level outline of what you'd recommend for Discover. Working on something related. Happy to chat by DM if you'd prefer.
