Youtube is more of a visual aid that's interactive! So, to answer your question my reply will have to be a definite YES. Going back to my definition of what YouTube is, I could say that it is interactive in a sense that, you can get in touch with the uploader of the video clip and give him or her a piece of your mind. Like perhaps, inform him or her of your feedback or share additional information regarding the video that the uploader posted. I am very thankful to the brains and brawns behind the creation of YouTube. I have learned and discovered a lot of stuff simply by tapping on a video clip. It's YouTube that made me come to know the wonders that baking soda could do to your health and it's also through YouTube that I found out the magic Rebecca Louise could teach you on how to make your legs thinner! Whenever I have neck pains, I just seek advice from the wholesome twosome tandem of geniuses namely Mr. Bob Schrupp and Mr. Brad Heineck. And Dr. Mandell also gave me amazing techniques to relieve my muscle pains. Countless Hacks and DIY's could make anyone's day right! So, for me, YouTube is not just a teacher, it's more of a reliable best friend!
