Twitter Adds Messaging to Vine to Compete With Facebook

Twitter Inc. (TWTR) said users of its Vine video application can now send their contacts private videos and other messages, stepping up competition with Facebook Inc. in the mobile-messaging market. The feature’s introduction means Twitter and Facebook both now offer multiple ways for their users to chat without using basic text messages. Twitter, which also lets users directly message one another through its main smartphone application, is adding the communication capability to Vine just months after Facebook’s Instagram mobile photo-sharing application made it possible for people to do the same.
