Twitter’s @biz & @jack on @pierstonight

On last night’s interactive, live, studio audience special edition of “Piers Morgan Tonight,” Piers Morgan interviewed the founders of Twitter, Jack Dorsey and Biz Stone, as well as several notable tweeters.

“It’s extremely humbling to see how quickly the velocity of the service has taken off, and it gets faster and faster every year,” said Dorsey. Said Stone: “It was immediately engaging to us…initially, many people just like you thought this was primarily a useless tool.”
