H&D has been organizing workshops since 2013, and along the way has established social-technical affinities that are loose and stable, temporary and ongoing. We met and befriended many practitioners and sister organizations since, and got acquainted with manifold, peculiar pedagogical formats, and experimental approaches to working, learning, and being together. This publication derives from an enthusiasm for the various ways collective learning environments take shape and grew out of a curiosity for the ways that such practices are shared across different localities, timelines, and experiences.
