It should have been obvious, but I didn't realise that the best thing about publishing a book would be when someone reads and critically engages with the work and then builds on it. Thanks to the authors!

My first piece on Leiden Madtrics comes out from a triple joy:

1. Joy of reading a thought-provoking book and listening to the presentation from @samuelmoore.org

2. Joy of discussing with others who actually care the research commons

3. Joy of writing together with Tanya, a PhD colleague at CWTS

Reclaiming the scholarly ecosystem: Reflections on the first CWTS research seminar of 2026 In the first research seminar at CWTS of 2026, Samuel Moore argued that Open Access publishing took the wrong path and proposed alternatives with a new ‘commons’ approach. As PhD candidates studying s...

🆕 New blog post: @realjoonha.bsky.social and Tanya Lee reflect on the CWTS research seminar with @samuelmoore.org earlier this year and expand Moore's view on Open Access publishing to broader research infrastructure and culture.
