Abstract 

Care is everywhere and yet, much of it goes unseen. From neighbourhood lending networks to online communities exchanging small acts of kindness, the informal, everyday practices through which people support one another form the connective tissue of social life. Yet technology research has largely looked past this quiet labour, focusing instead on care in hospitals, social services, and moments of crisis.

This dissertation brings everyday care into focus. Through five studies spanning systematic review, participant observation, social network analysis, and participatory design, it examines how ordinary people organise, sustain, and scale mutual support, from tight-knit Black church communities to loosely connected strangers on Reddit. Together, these studies reveal how the texture of relationships, the design of platforms, and the pressures of crisis each shape who gives care, who receives it, and whether it lasts. 

The result is a richer, account of care as a continuous collective accomplishment that communities build and rebuild over time.
