Probably the best website by Google. It is extremely useful for pretty much anything you want. Songs, how to videos, reviews of just about all consumer products, comedy, movies, etc. All in one place. The interfaces as easy as it gets and it takes no effort at all to figure out where you want to go. Search helps you find the video you want very easily, even if your query is vague. YouTube is perfectly integrated with Google so your Google searches help YouTube show you content you would be interested to see. Subscription to channels is easy. Buffer time is less, even when you have a slow connection, because YouTube can automatically determine the quality suitable for your current connection, saving you a couple of seconds. Now with 360 degree videos, you can live the video that youre watching. Subtitle feature is also available to make your user experience that much better.
All in all, there is nothing to dislike about this website. Amazing for entertainment and research, since lectures and teaching channels are also available.
