'There Has To Be a Lot That We're Missing': Moderating AI-Generated Content on Reddit | Proceedings of the ACM on Human-Computer Interaction Generative AI is altering how we work, learn, communicate, and participate in online communities. How might online communities be changed by generative AI? To start addressing this question, we focuse...

Our paper (honorable mention for best paper at CSCW) is here:

“What Reddit moderators are dealing with is what people all over the place are dealing with right now... a world where it takes incredibly little effort to create AI-generated content that looks plausible, and it takes way more effort to evaluate it" -- @travislloydphd.bsky.social

AI Slop Is Ruining Reddit for Everyone Reddit is considered one of the most human spaces left on the internet, but mods and users are overwhelmed with slop posts in the most popular subreddits.

The most human place on the Internet... Or is it?

Great story at @wired.com about the challenges faced by Reddit moderators and users due to AI content.

And, if you are a non-US citizen who did this work, you and your entire family will be banned from the United States. (I know this is incredible, but read the order—that’s what it says!)

Check out @isabelcorpus.bsky.social's fantastic thread on our paper studying the effects of a "write with AI" button on change.org! ✍️ Spoiler: the effects of AI aren't always positive.

#genAI makes your outputs more average. Obviously could be of benefit to some but certainly not to all. And in general, I suspect we can each make ourselves more valuable by being specialised in some way, so it may hurt more people than you might guess.

Not sure I'd characterize it this way; quality did in the past explain good performance. We are now investigating the quality question more deeply, but I expect that the answer is "quality helps but there are other factors" (also investigating; see our Discussion for some ideas).

Really excited about this 🔔new paper🔔 where we had a chance to leverage Change.org 's staggered rollout of a "write with AI" tool to causally (aka "once and for all") measure the impact of such tools on global platform outcomes. Summary: with AI, petition length ⬆️, homogeneity ⬆️, Outcomes ⬇️. More:

Good quote. And, we are on it!

We were especially interested in petitions that touch on local government where affecting change seems more likely. Similar outcomes.

Legally sanctioned harassment. McCarthyism 2025.

Power imbalance. But reviewer activity and performance should be made public!

Sadly, usually not even within the same system (cough SIGCHI cough cough), let alone across reviewer pools.

Also damning (and perhaps even more meaningful in retrospect) is how Jack was in there RTing Crystal1Johnson, revealing how the “new elites” of Twitter have long been high on their own supply (of disinformation). Jack just got his from the Gabbard wing of the “left” and now Elon from the hard right

Acting the Part: Examining Information Operations Within #BlackLivesMatter Discourse: Proceedings of the ACM on Human-Computer Interaction: Vol 2, No CSCW This research examines how Russian disinformation actors participated in a highly charged online conversation about the #BlackLivesMatter movement and police-related shootings in the USA during 2016. ...

Here it is, the most damning academic figure in the history of all figures: Russian IRA accounts deeply embedded in both sides of the 2016 Twitter BLM "discussion" (by @katestarbird.bsky.social & team, 2018).

THIS is what our information ecosystem supports. Twitter just made it 1% more visible.

Elon Musk’s Worthless, Poisoned Hall of Mirrors How X blew up its own platform with a new location feature

I have a lot to say about the X location feature/scandal but in the meantime @cwarzel.bsky.social is here to remind you that it was not a surprise (see next post), the incentives are misaligned, and the corporations generally do not want to fix it.

I don't know if @jilltxt.bsky.social does but I just heard her brilliant talk documenting what sounded like a similar problem

No but I can make it so they are uploaded less

To be clear for other readers, this was a story about independence, not perks

$7M grant from NASA, Schmidt Sciences to upgrade arXiv | Cornell Chronicle The funding will help arXiv – which is maintained and operated by Cornell Tech – finish migrating to cloud infrastructure and modernizing its code.

Many people don't know this but arXiv is maintained and operated by @cornelltech.bsky.social (that does NOT mean you can send me complaints or feature requests!)

Everyone in the community should be excited that arXiv got $7M to upgrade from Schmidt Sciences, NASA

Haha yes it is not perfect

Steve Job pulling a MacBook Air for the first time out of a brown office envelope

In summary, the moment captured here explains why I am now a professor.

I was visiting @destrin.bsky.social at (then) UCLA the day MacBook Air was first launched. Saw her turn to her admin and say "please get me one". Meanwhile, as (then) Yahoo researcher, to replace a broken mouse I'd need sign-offs from three different SVPs. Academia instantly became more attractive
