Do translations make us happy? How localization builds open source communities

Localization is often seen as a purely technical task, but for many contributors, translation work is deeply personal. It is about cultural identity, community belonging and keeping a language alive in fast-moving technical ecosystems. Working with the Spanish localization team for OpenTelemetry, I discovered that what brings people back is not only the desire for accurate terminology, but the joy of building something meaningful with others who share the same language. Contributing to localization OpenTelemetry motivated me to start a new Romanian localization group and inspire contributors who had never participated in open source before. This talk explores why localization communities thrive, what motivates contributors beyond the mechanics of translation and how language-driven belonging can open the door to new contributors in cloud native and open source projects. I will share practical lessons, common challenges, and strategies for creating or sustaining localization groups that make both software and humans better.
