    I’m glad to see a new platform that isn’t completely locked down, allowing analysis like this.

    The trend toward everything being a walled garden is unfortunate.

      I’m conflicted. I agree with everything you say but I’m concerned about Bluesky eventually being flooded with AI posts trained on its public dataset. Being open could very easily lead to downfall.

        I feel like LLM models have had the opportunity to be trained on a sufficient amount of social media posts at this point that it's unlikely to matter.

      hmm could you find the Github? I couldn't find it in the paper in the Code Availability section

        Is it "scripts.tar.gz. A collection of Python scripts, including the ones originally used to crawl the data, and to perform experiments. These scripts are detailed in a document released within the folder" in the OP?

        The "code availability" says it's released "alongside [the dataset]", which appears to be the OP.

          oh good eye, I didn't catch that

    Pollution of online social spaces caused by rampaging d/misinformation is a growing societal concern. However, recent decisions to reduce access to social media APIs are causing a shortage of publicly available, recent, social media data, thus hindering the advancement of computational social science as a whole. To address this pressing issue, we present a large, high-coverage dataset of social interactions and user-generated content from Bluesky Social.

    The dataset contains the complete post history of over 4M users (81% of all registered accounts), totaling 235M posts. We also make available social data covering follow, comment, repost, and quote interactions.

    Since Bluesky allows users to create and bookmark feed generators (i.e., content recommendation algorithms), we also release the full output of several popular algorithms available on the platform, along with their timestamped “like” interactions and time of bookmarking.

    This dataset allows unprecedented analysis of online behavior and human-machine engagement patterns. Notably, it provides ground-truth data for studying the effects of content exposure and self-selection, and performing content virality and diffusion analysis.

        "Personal data" that was voluntarily published on a public microblogging platform with the explicit intention to share it with the world?

          Would it make a difference if we were talking about articles on a news website? I'm kind of on the fence on this one but I can see the point of view that just posting something online doesn't necessarily grant the end user an unlimited license to use the data. Source code is another example; open-sourcing a project doesn't automatically give someone else the right to use that code in their own projects.

          Does Bluesky explicitly state the license the user will be publishing under (Creative Commons or whatever), or allow them to choose one?

            > Would it make a difference if we were talking about articles on a news website.

            News articles are pretty explicitly copyrighted and published for a commercial purpose. The websites make their terms clear when you visit. I don't think anyone can argue that it is legal to copy and distribute these articles, same as a book or movie or song.

            Data posted on Bluesky on the other hand is meant to be broadly shared using the AT protocol. It is quite literally a feature. If you create your own Bluesky client, for example, you aren't committing copyright violation by downloading someone else's posts on there. Similarly, you aren't going against any terms of service by consuming a firehose of data from an AT relay.

            • danparsonson an hour ago

              Right, that's why I asked about Bluesky's content license; just because it's not in your face when you visit, doesn't mean you don't have to abide by it.

              You understand that categories of usage are important, right? No-one is breaking the GPL by reading source code, but incorporating into your own codebase can be problematic if not done correctly. Similarly, human beings reading the data posted by a Bluesky user is not the same as aggregating and analysing the data of thousands of users. As I said I'm on the fence with this, but I do understand why someone might have a problem with it.

            The data is public by default. You know this when you sign up and use the service. This should inform your expectations of how the data will be used.

          • ronsor 2 hours ago

            Don't make it public then.

                Is it more entitled to observe public data than to willingly put data in the public and then expect to control the actions of others?

              • paxys 2 hours ago

                Is you reading my comment on HN also entitlement? I certainly didn't give you permission to do it. It may have some personal details that I don't want you to see. Why do you think that is okay?

    • yawnxyz 2 hours ago

      I wonder how much time it takes to run this / what the script is / how resource intensive it is? Bsky is public right, so do you get rate limited? Do you scrape or use an official API? So many questions

      Also, I feel like only recently there's been an influx of people who have actually interesting things to say so I'd love to see nextyear's dataset

        Not sure about bulk export but you can set up a full stream of all activity without even registering an account.

        • unshavedyak an hour ago

          Blows my mind that they can send that much for free.

      • ks2048 an hour ago

        I was checking out the Python API today (the "firehouse" via "atproto" package) and got 5000 posts in 7.5 seconds.

    Sound like this could be used to train an open source LLM.
