YouTube rolls out an in-app messenger to keep users on its platform for longer. Dana Wollman, Executive Editor at Engadget, explains why Google thinks this messenger is a priority for the company, even though she believes the company should be focusing on YouTube comment maintenance. She explains YouTube needs to be realistic about why people are leaving the app. Plus, Google Maps releases a beta version of a new Q&A feature, similar to Amazon. Will it be useful? Wollman explains the lack of real-time answering may deter people from using the feature.
