This document summarizes a presentation about designing social experiences and product design guilds. It discusses how (1) social experience design is distinct from interaction design in focusing on nuances of social interactions, (2) current approaches to social experience design are still pre-scientific due to a lack of generalizable frameworks, and (3) product design guilds aim to provide mentorship and collaboration outside the workplace to help designers progress in their skills and careers. The presentation also outlines frameworks for analyzing sociotechnical systems, social affordances, and the balance of "plazas" and "warrens" in community structures.
