Jack Dorsey, Twitter's CEO, also Tweeted later on in the day that the company is reorganizing how Twitter will work together for the next decade. So there could be some other moves in the executive ranks in the coming weeks and months, depending on what Twitter is looking to do in the near future. Twitter has been under pressure in recent years, as it has struggled to add more active users to the platform. The company has been adding all sorts of new features and has also been focusing heavily on video, which is similar to what Facebook has been doing. And the reason for this is because video ads drive in more revenue then a regular text ad on the site. And with Twitter still growing (or at least trying too), bringing in more revenue is a good thing, especially for shareholders.
