Who sees what you share.
One table for every kind of data on Dium, and every kind of person who might see it.
A Flow is a community on Dium. A Wave is a thread inside it, such as a question or a live session. A Room is a group of Flows that share members and DMs. Sponsors, exhibitors and speakers can have Pages.
