Which of the following was the original question posed by Twitter's creation?

The original question posed by Twitter's creation, "What are you doing?" captures the essence of the platform's initial purpose, which was to let users share their personal status updates in real-time. This question emphasizes the idea of microblogging, where users could broadcast brief snippets of their daily life to followers. This focus on immediate, personal updates was instrumental in shaping Twitter's identity as a platform for casual communication and social networking.

As the platform evolved, the overarching theme of sharing thoughts and experiences led to broader questions like "What is happening?" or "What can you share?", ultimately redefining how users interact and consume information. However, the foundational question aimed to tap into the spontaneity of personal experiences, which was crucial during Twitter's early development stages.
