Watch Party for Content Creators
A podcast style channel for content creators to be able to display their content easily from Discord.
A creator could set up a premiere/video from YouTube which would create an event. All users who join would be able to view the premiere/video directly from Discord. The video's wouldn't have to be propagated through Discord as it could simply make use of the how video Embeds are used.
Another cool feature would be streams from websites such as Twitch. Viewers would be able to just tap into the stream through Discord.
