Product manager Shimrit Ben-Yair, said "they created the feature, because her team believes it would result to even more sharing".
Messages will remain in a separate tab that can be accessed anytime. It gives people a quick way to send a message or share a link to an individual or a whole group of people.
This could be a way for YouTube to ensure users are spending more time on its website and an effort to squash current and upcoming [Amazon] rivals. In addition, it could cut out the middleman, mainly other chat and messenger app.
Only a lucky few are getting in-app messaging today, those who do get it can spread the feature further by inviting friends and contacts to chat. If you get the update or an invite, let us know below.
