- Reposted by Isabel Silva CorpusExcited to present a new preprint with @nkgarg.bsky.social: presenting usage statistics and observational findings from Paper Skygest in the first six months of deployment! 🎉📜 arxiv.org/abs/2601.04253
- Reposted by Isabel Silva CorpusI 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.
- 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. www.wired.com/story/ai-slo...
- 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
- To do this, we scraped 1.5 million petitions and leveraged the delayed release of the AI tool in Australia to estimate the causal impact of access to in-platform AI on petition text and outcomes (as measured through signatures and comments). 2/
- Lexical features changed: petitions written with access to AI were longer, with more complex and varied vocabularies. Petition language shifted: in the pre-AI period petition titles tended to use short verbs like “let” and “stop”; after AI introduction we saw the rise of “implement” and “urge”. 3/

- Reposted by Isabel Silva Corpus@davidingram.bsky.social covered @mantzarlis.com and my work on Grokipedia citations for NBC! much more to analyze here www.nbcnews.com/news/amp/rcn...
- Had a great time at CODE@MIT this weekend, and wanted to highlight a few (of the many) cool talks!
- @utopianturtle.top presented a causal framework for modeling algorithmically assisted decision-making, which the authors use to identify the ways academic advisors leverage non-algorithmic knowledge, and where advisors’ holistic approaches contribute to improved student outcomes.
- This is a really cool work demonstrating the value of human expertise in sociotechnical decision-making processes! 🔗: arxiv.org/pdf/2505.13325

View full thread@ziv-e.bsky.social's talk showed the gaps in which users are recommended content that is aligned with their values. This work definitely points to the importance of user agency in feeds! I couldn’t find the link to this paper, but some related work from Ziv here: 🔗: arxiv.org/pdf/2509.14434
