@bsky.app this is an example where if you want to provide a delightful user experience showing more content on swipe up either related to @petebuttigieg.bsky.social or the topic would make a lot of sense

@bsky.app when taps on the video an immersive viewer opens up. I recommend providing swipe up experience to show related videos preferably from the same author if available

Can we try to understand why these people did what they did and understand their point of view?

How should we change our social media behavior? I remember how privacy and anonymity were primary user requests on forums like #discord for instance

An openness to experiment: contrary to popular perception bigtech’s money earning machines have not shifted over to LLMs but there is a top to down increase in the willingness to experiment new things. There is a lot more situational innovation in bigtech now.

Your campaign was built around listening to people, aggregating their voice and channeling those into your mandate. I am wondering how you will continue to listen to people as mayor and in particular how you plan to use technology like LLMs to scale the endeavor. 🙏🏾

A big change is coming in recsys. Long ago ranking models were actually ranking when it was doing pairwise ranking. Then it became an estimator model in the era of VM. Can we unlock all the RL advances of LLMs by making ranking a reward maximizing model again. open.substack.com/pub/recsysml...

#LLM vs #RecommenderSystems (Part 2/3) 👉 recsysml.substack.com/p/recsys-ret... is about Retrieval. And this is where the analogy with LLMs becomes surprisingly tight. Core idea: Retrieval in recommender systems plays the same role as pretraining in LLMs. We show clustering > "Semantic IDs"

Just to play the devils advocate, in tech this used to be the advice but recently tech leadership culture has changed to the 996 style. Do you think that is temporary or a precursor of a norm?

For folks who are following the trend of “generative recommendations”, I’d love to know what you feel is the best ight version of semantic id in your domain. For instance if we were to build a feed ranking for Bluesky using generative recs what would the “semantic” id be?

Tesla Q3 2025 California sales were down 9% YoY despite the huge rush for BEVs ahead of the Sept-30th expiry of the $7,500 tax credit. The BEV market ex-Tesla grew by 29% YoY in Q3, causing Tesla's share of California's BEV market to drop from 57% in Q3 2024 to 48%. www.cncda.org/news/califor...

Do you see this as a natural conclusion of the relentless investment into “productivity” or a poor understanding of the incremental impact of the CEO? Unfortunately at higher levels there is just no data to compare and estimate incremental impact
