Dorsey steps down as CEO of Twitter. Co-founder and former Chairman Evan Williams takes his place. Williams makes a post on Twitter’s blog:
While the board of directors and the company have nothing but praise for where Jack has taken us, we also agree that the best way forward is for Jack to step into the role Chairman, and for me to become CEO. Jack will remain on the board and be closely consulted for all strategic decisions, while I take on day-to-day operations with the support of Biz, Jason, Greg, and the rest of this impressive Twitter team.
