“Dorsey and Mckesson did not find each other immediately.
“Honestly, nobody knew who [Dorsey] was. I said ‘I think it’s that Twitter guy,'” recalled Mckesson. So he took Dorsey’s picture and tweeted it. Dorsey noticed and started following him.
Dorsey noted how activists like Antonio French, a city alderman in St. Louis, were using Twitter and Vine to share what was happening on the ground in Ferguson.
McKesson, however, said six second videos weren’t enough. “I was really happy when Periscope came out. We were really happy when they bought it.” Through his connection with Dorsey, Mckesson became one of the product’s first 20 beta testers.
Ferguson propelled Mckesson into the spotlight and also created a friendship between him and Dorsey that endures to this day.”
