Before joining Twitter, Mike was the founder and CEO of Newsvine, the social news site acquired by MSNBC, the first acquisition in its history. Before that, Mike led the team at ESPN, redesigning the first mainstream media site to support web standards way back in 2003.I caught up with him a couple of months back (before his announcement to step down from Twitter) for a wide ranging interview where we discussed the design process behind Twitter's Moments, what to look for when hiring designers, and what the future of a Tweet might look like.
