What is X (Twitter)?

X (formerly Twitter) is a social media platform where users can post and interact with short messages called "tweets" (now called "posts"). It is commonly used for real-time information sharing, news updates, public discussions, and connecting with individuals and organizations globally. Users can follow other accounts to see their posts in a personalized timeline, and can engage by liking, re-posting, and replying to posts. It's also used for marketing, customer service, and various forms of content distribution.
