Same. What really seals the "echo chamber"-ness for me, is that they have a priority on their "about" page claiming they're serious about inclusion, yet it's still an iOS-only invite-only beta.
iOS-only aside, Clubhouse is one of the most diverse modern social apps I've been on. As a white man, I often seem to be in the racial or gender minority which is refreshing and helps me hear more interesting conversations and viewpoints.
