Interesting, the way this stuff works. According to the BBC Jack Dorsey merely has an opportunity to join the board of The Walt Disney company.
Shareholders will be able to vote on his selection at the company's annual meeting on 18 March.
However, he's already listed on the company's web site as being on the board.
Either way, congratulations to Dorsey and Disney as I think his insight will no doubt prove valuable to the company and its activities in the coming years.
