May I introduce Nat, Australia's Number 1 most subscribed Youtubers. She gets on average 400,000 views per video she does.
It is really interesting to watch the evolution of Community Channels format. One of the things that I have noticed about her videos in the last couple of month is the way that she is entering into a dialogue with her audience. As you can imagine it would be quite hard to respond to every single comment but the way she gets around this is by playing her favourite comments at the end of the video (Porno Music Time).
On this video from 2007 (when she was not playing viewers comments) she got 1,100 comments and 300,000 views
Since rewarding people with showcasing their comments with Porno Music Time, on a recent similar video with 300,000 views, she is received 5,000 comments.
Rewarding your audience for micro interactions is key to developing a strong community.
