Who doesn't like youtube for its content that appeals to yourself personally, however, it has become a bashing ground, and there are areas that should be removed such as HATE GROUPS- pro Nazi, pro Islamic Terrorism, and those that encourage the harming of people for hateful reasons. I think there are also a load of spammers there, that needs tidying-up. Overall, I enjoy it immensely and there are a lot of educational and tutorial courses. Youtube rocks!
YouTube is a great site, period. If you're ever bored, or are looking for something in particular (such as music, tutorials or news), YouTube most likely has it. There are some videos that are unsuitable for children, however, so if you let your kids browse YouTube, be warned.
Excellent site for information and entertainment. Besides musical video, I often go to YouTube for "how to" videos. It is also a great venue for product information. I went to YouTube when I was researching cell phones.
