[Please RT] I’m recruiting PhD students to work with me at @UW! I’m looking for students passionate about developing new *social media algorithms*, both broadly and within the scope of this NSF grant: tinyurl.com/395yfphd More info: faculty.washington.edu/msaveski/ @UW / @UW_iSchool
Lots of people in CS are (almost surely) GPT-ing their peer reviews arxiv.org/abs/2403.07183
Community Notes don't affect post ranking (and shouldn't, in general -- they often add useful context to correct posts) But we measured a ~25-35% drop in organic likes & RTs (& smaller drop in QTs, since QTs are sometimes dunks...) in an A/B vs. the same post w/o a note We may…
[Please RT] I’m recruiting PhD students to work with me at @UW! I’m looking for students passionate about using computational methods to study how social platforms can be reimagined to enable better conversations, bridge political divides, and reduce the spread of misinfo. >>>
📢 "Rank-heterogeneous Preference Models for School Choice" by @AwadelkarimAmel, @arjunsesh, Itai Ashlagi & Irene Lo. KDD'23 Paper: arxiv.org/abs/2306.01801 Summary video: youtube.com/watch?v=UGoefF… Gist: choice models of ranking use the same model at all positions. Can do better! 🧵
Some of the coolest research I’ve been a part of at Twitter- birdwatch has some lofty goals (including fully open source data and algs) for user-driven misinformation detection. Thanks to my awesome coauthors and collaborators!

🚨Birdwatch Paper Alert!🚨 I am thrilled to finally be able to share this paper with the detailed results evaluating how effective Birdwatch's bridging algorithm is!

Work done with an amazing team of coauthors: @stefanjwojcik @loafieee @nclarkjudd @DeliaMocanu @stephen_ragain @mbfhunzaker @kcoleman with loads of help from the Birdwatch engineering team!
In the spirit of transparency, Birdwatch makes everything and the kitchen sink public and open source. Today, we’re sharing a paper that details the research, analysis and outcomes that informed its development and helped us understand its performance. 📊
NFL all-time wins by franchise Chicago Bears 786 Green Bay Packers 785
they move fast
David Shaw is unquestionably the most overpaid coach in college football
Birdwatch elevates contributions from participants whose notes and ratings are consistently found helpful by others. Today we’re rolling out some updates to help strengthen Birdwatch against manipulation and prevent potential attempts to alter contributor standing and impact.
Simulation of a car getting smashed using gravity values for different celestial bodies:
We’ve been hard at work building a Birdwatch that people from different points of view find helpful. We’re seeing promising results, and starting today, a test group of people in the US will see the highest rated Birdwatch notes on Tweets.
Can Stanford give Shaw the axe before they hand it to Cal?
Fast-forward 5 years: “Let’s go to Adam Schefter, who has more details about the Bears-Steelers game that was fixed by gamblers in 2021…”
