This ACM CSCW paper shows that online groups requiring active participation commitments (i.e., that you post regularly) see double the contributions and retain users 4 times more (compared to groups with passive reminders). Prob very useful to OSS and Wiki folks.

Our paper on the effects of automated content moderation on Facebook (w @justincheng@twitter.com & @cervisiarius@twitter.com) was accepted at The Web Conference 2023! Will make a detailed thread soon, but you can already read the pre-print!

See you in Texas yeehaw (?)

This cool new preprint argues that third-party bot detection tools generalize poorly due to the lack of robust high-quality data.

In a new blog post, I argue that discourse on social media's (potentially harmful) impact is entirely ~vibes based~.

In this new blog post, I argue that to improve online platforms, we need to study content curation practices. That is pretty hard to do, but we should do it anyway :)

➡ Can large language models (LLMs) recognize convincing arguments? Kind of.

We propose evaluating LLMs' persuasiveness capabilities by measuring their ability to recognize whether an argument would convince a user with specific demographics.

Audience capture is understudied IMO. I find it fascinating because the term comes from IDW folks close to audience-captured influencers (somehow, they reinvented Rebecca Lewis's report). Plus, it is well aligned with findings that the algorithm is not radicalizing people.

🚨LLMs outdebate humans when given access to opponents' personal Information!🚨

In a pre-reg study (N=820), participants who debated ChatGPT had 81.7% (p<0.01) higher odds of agreeing with their opponents after the debate (compared to a human baseline)

Twitter hivemind, what are two algorithmic changes that allegedly impacted platforms greatly? E.g., In 2016, Twitter changed its feed to show content using a ranking algorithm.
