there has been an incident, where the whole org with all its repos had been deleted
as an owner you start receiving updates from all issues of all org repos, which really sucks (and only new-repo notifications come with instant-unsubscribe links)
I have myself been made an owner of the nodeschool org when contributing to the site and actually found being made an owner a bit overwhelming – mostly because it was unclear what responsibilities that brings
nodeschool has meanwhile split this into core team and local hosts
