Only one thing is bad about it and that is buffering. However it depends upon the internet connection but then also it is boring to see the youtube video buffering again and again.
Talking about my personal experience the fast streaming of youtube can be obtained by using some softwares.
I have used two software of which one is proxy software and other is youtube video accelerator.
So proxy softwares is :-
Puff the Magic Dragon
|Puff the Magic Dragon|
And video accelerator is
Speedbit Video Accelerator
Speedbit is used when you are visiting the website normally however if it is blocked visit the site through the puff the magic dragon and see the difference in buffering or may be it will not.
So use and give us your feedback.
