Ive been using Youtube for last 6 years and never get bored of this app as well as website.
Whenever I get confused in something I search on Youtube and get results very quickly.
Also very good entertainment source interesting web series, news, drama, Standup comedy and much more.
As well as all videos uploaded on Youtube are filtered and removes 18+ content and abusive content so it is very safe to all of us and very family friendly.
