Read the below passage, and answer the following questions: "You might've heard of Clubhouse by now. It's unlikely you've joined Clubhouse. That's because the new social media platform has built its reputation, in part, on exclusivity. What is Clubhouse? In short: Clubhouse is an audio-based social media app. The company describes itself as "a new type of social product based on voice [that] allows people everywhere to talk, tell stories, develop ideas, deepen friendships, and meet interesting new people around the world." Basically, you can jump in and out of different chats, on different subjects, in something akin to a live, free-flowing podcast. You can simply listen or choose to throw in your thoughts. The audio itself, however, doesn't leave the app. That's the main rule: There's no recording of conversations and they're not saved. Clubhouse is big with celebrities. Float around the app and you might hear folks like Oprah, Kevin Hart, Drake, Chris Rock, or Ashton Kutcher. They might even host chats. In some ways, that's part of Clubhouse's appeal. You get the chance to hear, and even participate in, unvarnished conversations with famous and powerful people. Other than celebrities, the app is seemingly focused on people it considers an elite clientele. The app apparently plans to expand to the general public soon. It says it hasn't done that yet for two reasons: It wants to build community slowly and it wants to prepare features that will help it handle larger numbers of people. "We are building Clubhouse for everyone and working to make it available to the world as quickly as possible," the app's site reads."
