I see it as informational videos, even for learning more about islam and seeing any lectures.
I use freeopenproxy.com, what do u use to unblock youtube?
its working perfectly :S
you can check other video sites like http://tune.pk/ or http://videos.buzzoye.pk/ or http://playit.pk/
You can use any proxy or proxy extension to open Youtube but its already opened in Pakistan.
YouTube is now running in pakistan , who said it is blocked ??
