Youtube is my favorite video sharing platform because everyone can share(post) their skills in videos and make others learn great extent. My personal experience with youtube is pretty much good, I have learnt many things in a little time in youtube by watching videos. So there are some points that everyone likes:
Learning by just watching videos of your interest.
anyone can make channel to share their skills to high number of people and they can earn simultaneously
So learn and earn in this single platform makes it much more good than anybody can expect it to be.
It increases the amount of conversation among audience and channel owners that results in more connected world.
Finally, there is one thing that needs to be corrected and that is the inappropriate content posting, this content is not suitable for children and teenager.
