I'm still new to Clubhouse and trying to understand the appeal. Is Clubhouse basically like the old radio call-in talk radio (live talk radio shows) where you basically can have your audience "call in" and join the hosts? Is it anything more than live podcasting with an audience that can also be made to be guests and you get their reactions? Am I missing something? Or is Clubhouse more of a free-for-all group voice chat with no real leader, like just getting onto a Discord channel and talking? Clue me in!
