Step 1 : Introduction to the question "The current CEO of Twitter uses what Twitter handle?"
@Jack is of course Jack Dorsey, the CEO and co-founder of Twitter. Dorsey first came up with the idea that he developed as Twitter while studying at NYU. Twitter is often described as the "SMS of the Internet". In its early days, Twitter was referred to as twttr. On this day in 2006, Jack sent the first tweet, which read -- "just setting up my twttr." The service rapidly gained worldwide popularity. Twitter is now one of the most popular social media platforms, with over 100 million daily active users and 500 million tweets sent daily.
