Are Vimeo, Dailymotion etc. also banned? If not, that ban is retarded because those are sites with a similar service and should be treated equally. BTW, if you do not like Youtube simply stay away from it, there is no reason for the government to ban it (I think it is as harmless as for example this site). And oh, please do not say it is because of "attacking Islam", because Youtube never attacked the Islam, users of the service did.
BTW, just my 2 cents, no offense intended.
