Most of us have they favourite Youtuber that you watch over and over. There are a lot of people who upload videos on YouTube to grab the attention and to have their own audience. But to became famous YouTuber you have to engage with the audience and be attractive to them.
First and the most popular thing which YouTubers do is Q&A in many different ways. The most popular are asking to write questions as a comment. However, YouTubers are people with imagination, so your favourite YouTuber might give you his phone number or ask you to write the question on the photo and send by Snapchat (yes, I saw that kind of Q&A).
All of the YouTubers who became famous did it thanks to their audience. My favourite example is YouTuber from my country, whose video has more than 150 million views. The video with his dog turned into a spider was shown in many countries. There is even a Wikipedia site just about that video (here) .
This example shows how audience participation and engagement can change someone’s life. Without audience participation, especially online, we would not have YouTubers, because what they do, is to please the audience.
