Twitter has updated their iOS and Android mobile apps along with the TweetDeck app for Google Chrome with a focus on direct messaging. The Twitter apps now have links to Direct Messages in the tab bar and lets you send photos inside direct messages. Many brands and celebrities like to communicate with their fans and customers through direct messages rather than publicly on Twitter. For example, I communicated with Delta Airlines through direct messages when I talked to them about a recent mishap that took place. “Discover” is no longer in the main view as it has been put within the Timelines feature. A new Mac version of the Twitter app will be coming soon after getting approved.
