They actually did mention the Teams feature, in the 3rd paragraph under “The Community” heading.
And to stoke collaboration between content creators that v2 calls “artists”, there’s a Team feature. “A Team’s profile page will list its members, and the members have the ability to promote and repost Team posts to their own timeline (even with alternate captions)” Hofmann explains. The collaboration behavior, where artists appear in and promote each other’s videos, was popularized on Vine since videos took so little time to create and many artists lived close to each other in LA. The team-ups led to some of the app’s most creative content, so v2 is hoping to facilitate co-starring.
