It was a defining moment for Clubhouse. The app’s servers trembled under the weight of tens, if not hundreds, of thousands of listeners simultaneously flocking to the platform to hear about Tesla founder Elon Musk. Members briefly panicked when the “room” he was speaking in quickly filled to its capacity of 5,000 listeners and bounced people trying to enter. Within 10 minutes, “overflow” rooms began to appear that the Clubhouse led Elon into. The platform performed poorly but managed not to collapse.
