Odeo went out of business in 2006, so Dorsey returned to his messaging idea, and Twitter was born.

Appearing on a podcast run by a health guru who previously said that vaccines caused autism, Dorsey said he eats one meal a day and fasts all weekend. He said the first time he tried fasting it made him feel like he was hallucinating.

"It was a weird state to be in. But as I did it the next two times, it just became so apparent to me how much of our days are centered around meals and how - the experience I had was when I was fasting for much longer, how time really slowed down," he said.

The comments drew fierce criticism from many who said Dorsey was normalising eating disorders.

Dorsey would regularly don leather jackets and slim suits by Prada and Hermès, as well as Dior Homme reverse-collar dress shirts, a sort of stylish take on the popped collar.

In a bizarre Huffington Post interview, Dorsey was asked whether Donald Trump - an avid tweeter - could be removed from the platform if he called on his followers to murder a journalist. Dorsey gave a vague answer which drew sharp criticism.
