Lots of people in CS are (almost surely) GPT-ing their peer reviews

@robertmays Column B incoming, George McCaskey cycle of QB/HC/GM misalignment continues

[Stephen Ragain @stephen_ragain]

@AdamSchefter Now they can draft a QB with a lame duck HC. Then next year they can fire Poles and Flus when that doesn't pan out.

Following that, a coaching search where Bill Polian and Ted Phillips outvote Kevin Warren to hire an HC running an outdated defense while the new QB busts

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 be getting some of the best of both worlds: an organic reduction in spread when users voluntarily decide to share misleading content less after being more informed, without censorship.

📢 "Rank-heterogeneous Preference Models for School Choice" by @AwadelkarimAmel, @arjunsesh, Itai Ashlagi & Irene Lo. KDD'23 Paper: https://t.co/d581neVZv4 Summary video: https://t.co/ILb42SF1VS Gist: choice models of ranking use the same model at all positions. Can do better! 🧵

@ColtSmith18 Terrible pick so far, I knew they were actively tanking when they brought him back out to return/muff kicks again

[Stephen Ragain @stephen_ragain]

@adamjahns Looks like they got the message from the Quinn trade- Poles wants them to tank

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!

[Jay Baxter @jaybaxter]

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!

@ShamsCharania I was wondering why the Vegas wins line seemed a little low
