Great advice here, if just want science, no drama, no politics, no hot takes:

Yes, "Top Scientists" is a bit of an over-promise. As for that one outlier, that might be me. I study networks for fun, but don't engage much in social media myself. The many follows are part of the experiment; I bulk follow or unfollow from time to time. Hope nobody minds.

Yes, we considered many variations of the metric. It's hard to come up with something that's simple, standard, easy to implement, etc. Suggestions more than welcome

Nice. From the docs, I was convinced that you would only ever get 100. So that a second requests would just get you the same 100 posts again. But if you got 500 unique posts, I was wrong. Working in R too, btw. github.com/bluesky-soci...

Maybe I should put everybody on a list. (Haven't tried lists before.)

"Mutually comment relationship" -- is that if two users both comment on each others post? There's a limitation in the API, you can (I think) only get 100 posts and replies per user, so that complicates things a bit.

I don't disagree. Maybe the list name is a bit off; full name is "Influential Members of the Science Community", but when that gets awkward, sometimes we do "Top scientists" or similar.

Good observation. Posting activity and post content are not criteria for the algo, imperfect as that might be

08.09.2025 14:36 πŸ‘ 1 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

Sorry no, for this to work, we really need an hard, rule based algo, imperfect as it may be

08.09.2025 13:15 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

No, the full thing is not available, sorry. I'm considering if it should be, somehow.

Scientists on Bluesky - A Simple Algorithm to Build a Network from Bluesky

Hi @joehodson.bsky.social, you made it to list of the science community, because the algo included you. Likely because you follow or are followed by people in academia, and include a few terms that are sometimes associated with academia/science/research. Full methodology is explained at the site.

Scientists on Bluesky - What are they posting?

My favorite side project these days: Analyzing the Bluesky Science community (with @mkeyoung.bsky.social). Just finished a write-up of an angle not explored until now: A look at the most popular posts from the most influential network members. Lots of examples and some funky graphicsβ€”fun to explore!

Thank you for the kind words @johnbohannon.bsky.social

Scientists on Bluesky - Compare Newer and Older Net

Great question, thanks for asking. Both biologist and physicist are in the list of keywords, but that doesn't mean the list is perfect. This note has a description of how we expanded the list in the latest iteration. It's all work in progress. lassehjorthmadsen.github.io/blueskyanaly...

Good point, will add archaeology as a key term for next iteration. πŸ™

Ingen eksplicit skelnen mellem "scientific" og "academic". Det afgΓΈrende er, om man bliver fulgt af tilpas mange fra det videnskabelige miljΓΈ, OG har en beskrivelse der smager af videnskab/akademia/research

Together with @mkeyoung.bsky.social, I had a first go at establishing and analysing a Bluesky network of researchers. Have a look at the top-100 list of most influential researchers, and the mesmerising 3d-visualisation here: lassehjorthmadsen.github.io/blueskyanaly...

Friends, I wrote up a quick guide to getting started on Bluesky for folks who are used to old Science Twitter.

Please share it with your folks who are joining. And please let me know if I missed anything or got anything wrong. πŸ§ͺ

Spent some time working with the Blue Sky Social API recently and having a lot of fun. Especially when comparing to the costly X API that overpromise and underdeliver.

To everyone who wonder why I just followed them: Together with @mkeyoung.bsky.social I'm researching how professional networks form on social media. I might follow or unfollow a large number of users from time to time. Feel free to follow back; will post updates on the project.
