Alan Said @alansaid.com · 02/09/2026Please get in touch if you are interested, or if you would simply like to discuss whether a location might be a good fit for a future RecSys. 010
Alan Said @alansaid.com · 02/09/2026We also welcome expressions of interest in hosting future editions beyond 2029. More information about the process is available here: recsys.acm.org/steering-com...recsys.acm.orgRecSys – ACM Recommender Systems 110
Alan Said @alansaid.com · 02/09/2026There is no need to prepare a full conference bid before reaching out. We would initially like to hear about the proposed location, prospective General Chairs, their involvement in the RecSys community, and relevant conference-organizing experience.recsys.acm.orgRecSys – ACM Recommender Systems 100
Alan Said @alansaid.com · 02/09/2026We are already in conversations with prospective organizers about possible locations for 2029, but we very much encourage others in the #RecSys community to get in touch with me or anyone on the RecSys Executive Committee (@drchole.bsky.social, Humberto Corona, @md.ekstrandom.net).recsys.acm.orgRecSys – ACM Recommender Systems 122
Alan Said @alansaid.com · 02/09/2026With #RecSys2026 and #RecSys2027 taking place in the US, followed by a European edition in 2028, the @recsys.bsky.social Steering Committee is currently looking beyond these regions for #RecSys2029.recsys.acm.orgRecSys – ACM Recommender Systems 154

Alan Said @alansaid.com · 31/03/2026Coordinating this meeting is not simple, though. We are in 9 time zones, from UTC−7 to UTC+11, which means some of us are starting very early while others are staying up far too late just to make it work. 100
Alan Said @alansaid.com · 31/03/2026It's always more fun to meet face-to-face, but these meetings are still a great chance to reconnect with familiar #recsys peers. 100
Alan Said @alansaid.com · 31/03/2026While we usually meet in person during the conference, this virtual check-in is an important moment to discuss the upcoming conference and the broader direction of the #RecSys community. 100

Alan Said @alansaid.com · 04/01/2026I've received phone calls and voice mails that all seemed to be intended for someone else.

Alan Said @alansaid.com · 02/01/2026Across talks and public conversations, the same questions kept coming back: #sustainability, #accountability, and the longer-term consequences of recommender systems (#recsys). Seeing this work travel outside academia was a good reminder of how careful we need to be with nuance. 120
Alan Said @alansaid.com · 02/01/2026Wrapping 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. 110

Alan Said @alansaid.com · 16/12/2025I 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. 161
