Groups you talk to.
Organizations you talk about.
So far, all Groups ard Organizations are companies, but Groups can be any set of people you want to tell stories with. And you can tell stories about any mix of Organizations, Events, Themes, and People...all four of those ways to organize stories. And more are coming.
I am currently running everything wide open and pre-enrolling you all to relevant Groups. Eventually, folks will join the site by being invited to a Group. Group moderators will decide Group membership and Private vs Public settings for content.
