Layers, cells, and constellations: Jon Henner's Twitter platform as crip activism.

This article analyzes the Twitter presence of Jon Henner (@jmhenner) as a form of crip activism and public scholarship that challenged normative ideologies around language, disability, and deaf education. Henner, a Jewish deafdisabled autistic scholar and parent living with advanced melanoma, used Twitter to connect diverse communities, critique ableism and racism in deaf education, and advocate for disability justice grounded in intersectional, anticapitalist, and feminist politics. His tweets exemplified crip authorship through multimodal, accessible communication and fostered cross-disciplinary dialogue, community building, and solidarity among disabled, deaf, and marginalized groups. The paper also reflects on Henner's legacy and calls for ongoing engagement with his work as a model for transformative scholarship and activism.
