Together with @abellogin.bsky.social, we analyzed the papers published in the @recsys.bsky.social Reproducibility track from its inception in 2020 until 2025. The results have just now been published in our paper "Reproducibility in Recommender Systems: A Survey" dl.acm.org/doi/10.1145/... #recsys

Reproducibility in Recommender Systems: A Survey | ACM Transactions on Recommender Systems

Reproducibility has become a cornerstone of credible recommender systems research, driven by growing concerns about the reliability and generalizability of experimental results. In response, the ACM R...

Recommender systems research goes beyond what we see at @recsys.bsky.social. BEYOND is a space for interdisciplinary work, new perspectives, and conversations that complement the algorithmic focus of the conference. beyondrecsys.github.io/2026/ @evazangerle.bsky.social @christinebauer.bsky.social

Occasionally, over the last 15 years or so, I've received invitations to literary events, notifications of awards for literary works, inquiries about my work in relation to the Swedish Author's Fund (Sveriges författarfond), invitations to contribute translations to collections of poems, etc., etc.

Wrapping up 2025 and realizing it was mostly a year of transitions. Stepping away from Head of Education role after 6+ years gave me some distance, and a lot to think about in terms of what actually makes change stick. Less about structures, more about continuity, trust, and people.

I see @acm.org has added an additional page at the beginning of all papers in the ACM Digital Library. Assuming this is part of the move to #ACMOpen. I wonder if any estimates of how many additional printed pages that will be wasted as an effect of this have been made? Doesn't seem very sustainable.
