What was the primary purpose of creating Twitter?

The primary purpose of creating Twitter was to allow users to share brief updates about their current activities, encapsulated in the platform's original tagline: "What are you doing?" This concept emphasizes the idea of microblogging, where users can communicate quickly and succinctly with their followers. The platform's 140-character limit (later expanded to 280) was designed to encourage concise messages, making it straightforward for users to articulate their thoughts or activities in real time.

This focus on personal status updates not only facilitated social connections but also became foundational to Twitter's evolution into a broader platform for sharing news and information, though that wasn't the initial intent behind its creation. The engagement and interaction fostered by status updates allowed users to connect and share their lives, leading to the development of social networking features over time.
