The drawback with Youtube is you might get more than you bargain for with unnecessary exposure and trolling but it all depends on how you set up your account.
Youtube is so addicting because you can watch anything you want like anytime. I have a friend that swears by Youtube. Sometimes I think he needs a mental check because he believes everything he sees on there. Some of it is just made up stuff to get views.
I was extremely disappointed when Google took over Youtube.
Every video starts with an ad rather than the one ad for every ten videos with the old Youtube.
Also, the new message system is far inferior to the old private message system Youtube had before Google ruined everything. Youtube had an Outbox and an Inbox just like a regular forum. But now, everything is messed up. I can't even find the Outbox in order to check my sent messages.
It took them long enough to do that. I know there is free speech but free speech does not override recruiting for the purpose of killing people. They should have done this before.
