Youtube?

YouTube is a website that has now raised the number of people who like it and people that does videos. I leave a different advantages and then a few disadvantages.
It is a good resource for everything you need, if you want to watch a tutorial to learn something (as if the studies is as if something in our daily lives, such as care for our hair, etc. ) to search for a song and its lyrics or a song sung by yourself, watch videos for entertainment, laugh or people tags / challenges, to upload videos giving a personal opinion on any subject or talking about oneself, can also be daily blogs (record what you do on your day to day), is an environment where many people is advertising, etc.
There are many good things that you can do, but there I say other bad things also happen in youtube.
There are people who use videos against yourself threatening you; once you have uploaded several videos of yourself, you're making public your life and if you get to a point where a lot of people know you, wherever you go there will be people who will ask for a photo or autograph as if you were famous, at the beginning it seems a good thing to be recognized for what you do, but in my point of view is also something stressful, because you can not lead a normal life, because maybe journalists including will wonder about something interesting in your life to publish and it's something that usually don't like; comments have no censorship, so you can receive good and bad critics worldwide.
As you can see, there are a lot of things that can happen with youtube that are useful but care should be taken with the content.
