I'm in Barcelona for #CHI26, presenting my paper "Beyond Community Notes: A Framework for Understanding and Building Crowdsourced Context Systems for Social Media" Friday in the 9am "Community Governance and Moderation" session. @chi.acm.org dl.acm.org/doi/10.1145/...

"Community Notes" are reshaping how millions encounter information on social media--but what makes them work (or not)? We term these "Crowdsourced Context Systems" (CCS) and introduce a framework for designing and evaluating them in a new #CHI26 paper 🧵

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

Spotify is garbage on every count: Its treatment of artists, its ICE advertising, the CEO's investment in military AI, its leading role in the commodification and AI slopification of music, its terrible audio quality—you name it. So I quit, and put together a complete guide to getting off Spotify:

Excited to share a new working paper! What happened when Change.org integrated an AI writing tool into their platform? We provide causal evidence that petition text changed significantly while outcomes did not improve. 1/ arxiv.org/abs/2511.13949

I spoke with @kattenbarge.bsky.social for this @wired.com piece about my research into reddit moderators' experiences moderating AI-generated content. Moderators are working hard to keep Reddit "one of the most human spaces left on the internet," but it's a trying and often thankless task.

🇳🇴 I'm in Bergen for #CSCW25 🇳🇴 This Wednesday, in the "Content Moderation" session, I'll present my paper about how Reddit moderators are grappling with AI-Generated Content. I'm honored that it received a Best Paper Honorable Mention 🤓 If you're here too, let's connect! dl.acm.org/doi/10.1145/...

New preprint! Crowdsourced Context Systems (CCS) like X's and Meta's Community Notes are popping up on various social media platforms. How can we better understand, critique, and design such systems?

I'm at Seattle 4S! I'll be part of the "Risks of 'Social Model Collapse' in the Face of Scientific and Technological Advances" panel Friday morning, discussing online community governance of AI-generated content. Would love to meet others studying AI's impact on the info ecosystem! #STS #4S

It was a pleasure to present our (@jennahgosciak.bsky.social @tungdnguyen.bsky.social @informor.bsky.social) large-scale study of Reddit community's AI rules in the AI Ethics and Concerns session at #CHI25! The paper is now available open access in the ACM library: dl.acm.org/doi/10.1145/....

Thankful for @sarahagilbert.bsky.social's thoughtful words on the ethics issues here: a must read for all researching online communities.

*NEW DATASET AND PAPER* (CHI2025): How are online communities responding to AI-generated content (AIGC)? We study this by collecting and analyzing the public rules of 300,000+ subreddits in 2023 and 2024. 1/

*NEW PAPER* How are online communities adapting to the presence of AI-generated content (AIGC)? To answer this question we collected the community rules for 300,000 public subreddits and identified rules governing the use of AI. /1
