Also, the playlist bar automatically plays an entire playlist once you begin watching one of the videos from the selection, which provides another opportunity for more than one of your videos to be played in front of a user who you’ve already gotten the attention of. This feature doesn’t come off as abrasive because it’s very easy for a user to stop, play, pause, skip or return to your YouTube channel by interacting with the playlist bar at the bottom of the browser at anytime.
I do not think this is how most people use YouTube. YouTube videos are more like blog posts, and fit more effectively into the niche of content marketing. Sure, people will comment—but they do so in a manner similar to how they comment on blog posts. They come to view and digest videos, not necessarily share their thoughts about the day. Because of this, you should approach YouTube as content marketing instead of social media marketing.
