I regret missing #atmosphereconf but would love attendees to check out and give feedback on our labeler at @stechlab-labels.bsky.social -- a first-pass implementation looking at how labelers can improve the surfacing of transparent, objective, useful ATProto information about account behavior.

So many good science-oriented features on the upcoming Lea browser, presented at #ATsciemce by @mariaa.bsky.social. #Atmosphereconf.

We did a pregame #ATScience meal with (L->R) @byarielm.fyi, me, @mariaa.bsky.social, @verime.coop, Francisco Carvalho, @ronentk.me, @tgoerke.bsky.social, @sjgreenwood.bsky.social The sushi at Syu Kitsilano was amazing! Get their Green Cali Rolls! #AtmosphereConf

I'm on my way to Vancouver for #atscience #atmosphereconf! Social media can be different. The internet can be different. We don't have to accept what companies have constructed; we *do* have agency to build, hack, repair, nurture, grow, create! So excited to meet my bsky heroes and learn more!!

Introducing skytrails by @kennypeng.bsky.social, a way to browse posts across Bluesky! Follow trails to navigate the space of content/conversations here, and discover new interests beyond your usual feeds 🕸️ I'll talk more about it tomorrow in my talk at #atscience #atmosphereconf!

delighted to be back (home) in vancouver for #atmosphereconf and #atscience! lmk if you'll be around and let's chat about custom feeds / social media research / scientific engagement on atproto :)

Wonderful to work with co-first author @sidhikabalachandar.bsky.social along with Alex Chouldechova, James Diao, Kadija Ferryman, Arjun Manrari, @stephenpfohl.bsky.social, Neil Powe, @rajiinio.bsky.social, and @emmapierson.bsky.social on this piece. You can read it here! rdcu.be/e9uZa

Great news! Building a feed on Graze got way easier today. Our prompt-based feed generator got a massive facelift over the weekend, and can now help you create the perfect feed using plain language (like this feed about ATProto without any mention of @jcsalterego.bsky.social). Come give it a try!

I'm hiring a postdoc at @cmu.edu (w/ far.ai & @dgrand.bsky.social + @gordpennycook.bsky.social)! How do LLMs shape human beliefs — and what do we do about it? AI safety meets behavioral science. Open to technical and social science backgrounds.

Wouldn't it be nice if events you find posted on @bsky.app could automatically get added to your calendar? They can now. 👇

it's a tough competition but this is my favorite paper from @kennypeng.bsky.social so far-- studying the language model linear representation hypothesis through the lens of compressed sensing 👀 arxiv.org/pdf/2602.11246

New paper! The Linear Representation Hypothesis is a powerful intuition for how language models work, but lacks formalization. We give a mathematical framework in which we can ask and answer a basic question: how many features can be stored under the hypothesis? 🧵 arxiv.org/abs/2602.11246

Ten math problems with proofs known the authors. Proofs are encrypted until Feb 13. For all problems, authors claim both AI-based literature searches and zero-shot attempts at proofs failed. If you want to take a crack, you have until next Friday (2/13)!

@mariaa.bsky.social and I have been building a custom client that we'd like to make public in the near-term BUT we want to make sure we've gotten the security right. Anyone with some expertise open to helping us out a bit?

Opus 4.6 is very powerful

🎙️ I had a great time joining the Data Skeptic podcast to talk about my work on recommender systems If you're interested in embeddings, aligning group preferences, or music recommendations, check out the episode below 👇 open.spotify.com/episode/6IsP...

"While almost everything that astronomers study occurs in the vacuum of space, astronomy itself does not 'happen in a vacuum'. Interactions between scientists, as well as outreach to members of the public, improve extensively from access to good communication tools." Paper day! ⤵️

For You has become the most liked feed: bluefacts.app/feeds/top Thanks everyone who gave it a like! Liking a feed may seem meaningless, but I think it does matter to the feed creators. It definitely has been motivating for me. Consider going over the feeds you have pinned and giving them a like!

Check out our new paper at #AAAI 2026! I’ll be presenting in Singapore at Saturday’s poster session (12–2pm). This is joint work with @shuvoms.bsky.social, @bergerlab.bsky.social, @emmapierson.bsky.social, and @nkgarg.bsky.social. 1/9

If you want to research or even just learn for yourself about "Social Media, LinkedIn, Facebook, Instagram, Youtube, WhatsApp, or Twitter," then yes, unfortunately, it's almost impossible to do that research externally. This is a big reason why Bluesky's open ecosystem is so exciting to me!

What's the point of doing science if you can't tell anyone about it? We are excited to announce @emily.space as another confirmed speaker for #ATScience!

Hello all! 👋 I’m delighted to share a 🚨 new preprint 🚨: “Active Evaluation of General Agents: Problem Definition and Comparison of Baseline Algorithms”. A paper thread! 🤩📄🧵 1/N

Excited to present a new preprint with @nkgarg.bsky.social: presenting usage statistics and observational findings from Paper Skygest in the first six months of deployment! 🎉📜 arxiv.org/abs/2601.04253

If you know people in Theoretical CS or adjacent who just joined BlueSky (or just did yourself), please tag them or say hi in this thread! #TCSSky (I'll follow them/you, let's strengthen our research community here)

🔈 Asu Ozdaglar and I are hiring a postdoc for next year to work on adaptive, ethically-informed decision systems, human–AI collaboration, and decision-making under uncertainty. More info here: charapodimata.com/postdoc_anno...

so so so excited to present our research + connect with the #ATScience community 🧪🎉

If you are a senior researcher (i.e., associate prof level or later), and you're interested in moving to the University of Waterloo (best CS program in Canada) for the Canada Impact+ Research Chair (biggest chair position in Canada, $$$$$), email me. Discretion guaranteed.

I'm going to start doing this every month to help new users dipping their toes in. If you post about AI research here, like this post. I'll follow you. (Like even if I already follow you, to help others find you too.)

That said, we know people want more safety tools, so @eugenevinitsky.bsky.social and I are building them! Here's what that looks like in our client. My post got a lot of interactions and then a big account reposted it, so alerts showed up and I have tools to deal with it. Give us more ideas!

@eugenevinitsky.bsky.social and I are looking for a few testers for something special we've been building! It's an app that lets you view the same content you see here on Bluesky but with extra features — some focused on researchers, some general upgrades. Reach out to us if interested!
