Twitter and Square cofounder Jack Dorsey is the newest member of Disney's board of directors. The Mickey Mouse company announced as much on Monday afternoon, and said he's acting as an independent director "effective immediately." The man better known as @jack -- Twitter's first human user and its standing executive chairman -- tweeted a quote from Disney's founding father, Walt, to commemorate the announcement: "I only hope we don't lose sight of one thing -- that it was all started by a mouse."

Dorsey will bring his entrepreneurial and technological perspective to Disney. Company head Bob Iger said of the appointment, "The perspective he brings to Disney and its Board is extremely valuable, given our strategic priorities, which include utilizing the latest technologies and platforms to reach more people and to enhance the relationship we have with our customers."
