A few weeks back I gave a talk at Stanford about some of our work on generative AI in the online social world.

The video is at https://www.youtube.com/watch?v=IH-hRdNMIq0

Preprints of the work are at:

This is a set of software tools designed to do conversational AI field experiments. It recruits and consents Reddit users, assigns them to conditions, manages and store their conversations with chatbots, and tracks their public behavior before and after the intervention. This allows researchers to track longer-term changes to behavior in a real-life setting.

The paper describing the tool and making an argument for its benefits (and delineating some of the risks and drawbacks to this approach) is out in Computational Communication Research: https://www.aup-online.com/content/journals/10.5117/CCR2026.2.5.FOOT The open source GitHub project is at: https://github.com/jdfoote/Reddit-Conversation-Laboratory We (me, Loizos Bitsikokos, Hitesh Goel, and Deepak Kumar) hope that this paper and library make it much easier for others to pursue this kind of research. Contributions and pull requests to the project are very welcome!

I am recruiting PhD students this year!

If you are interested in studying the organizing and self-organizing processes of online communities, the role of AI in online communities, and/or how communities influence their members (and vice versa), then you should come to our research group's info session.

Details are at https://blog.communitydata.science/prospective-phd-student-qa-september-26th/ , including a sign-up link.

You should also reach out to me - contact info is on my website - https://jeremydfoote.com/

The TL;DR is that founders differ along a lot of dimensions regarding why they start their subreddits and what they hope they become. Those who are motivated by interest in a topic, and who have plans to recruit others are the most likely to see their communities grow. To learn more, read the blog post, or better yet, read our paper at https://arxiv.org/abs/2405.00601 which will be presented at #CHI2024

@jessamyn We can't know for sure without looking at other platforms, but many of the results match up pretty well with my earlier work on wikis (https://dl.acm.org/doi/10.1145/3025453.3025639) so I think it's a good guess that the main ideas would apply in other similar platforms.

@siim @skairam Good question. Sanjay ran those analyses so he can correct me if I'm wrong, but every time you look at this kind of activity data, it's heavy tailed, so most subreddits had single digit contributors, some had tens, some may have had hundreds. But in just the first month, most would have been very small.

@lutindiscret I think there are some implications for sure. For example, @sohw led a paper about small subreddits and how they benefit from connection to similar big subreddits. @groceryheist has done lots of work around ecosystems of communities. I think there are network effects where you need a critical mass before people move over.

@dyutibound I hadn't thought about it this way. There's definitely a tension of wanting prospective students to know about the negative aspects of the job (and the difficulty of landing a job!), but I can see how that acts as a form of gatekeeping.

@andrewiliadis@mastodon.world Are you at AoiR? One of my students is there and you should totally meet her if you are.
