Newly crowned Twitter CEO Jack Dorsey came to fame as a co-creator of the microblogging service, which limits messages to 140 characters. But even with his emphasis on brevity, he’s rarely at a loss for words.
Dorsey is now starting his second stint as Twitter’s CEO. He became the company’s first chief executive in May 2007, holding the post for 16 months. The 38-year-old is also the CEO of Square, an Internet-payments company, and sits on the board of media giant Walt Disney.
To mark his reinstatement, we went searching for his best and most notable quotes. Here’s a list of some of our favorites, starting with the famous first tweet itself:
“Just setting up my twttr” — @jack on Twitter, March 21, 2006
“Make every detail perfect and limit the number of details to perfect.” — @jack on Twitter, December 2010
“It’s really complex to make something simple…I’ve always been fascinated by cities and how they work. And I taught myself how to program so I can understand how the city works.” — “Charlie Rose,” January 2011
