I don't think the PR in DataCenter is permanent. They will finalize it one last round before release.
It is PR3 on three datacenters so far. http://digpagerank.com/index.php?url=www.youtube.com&dc=18 72.14.217.104 , 72.14.221.99, and 209.85.135.102
this is obviously an error, there's absolutely no way that youtube.com will be a pr 3. google.com is also showing as a pr n/a on those 3 datacenters. so let's all take a bit of a chill pill
-Quite off topic- Are you trying to say that an <embed> counts as a link? I'm not going to argue youtube has a lot of backlinks but I'm pretty sure 'Every video embedded' doesn't equal a backlink. See youtube's Embed code: <object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/J51G4Z-bjV4&rel=1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/J51G4Z-bjV4&rel=1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object> Code (markup):
Very simple explanation, go to http://youtube.com - it's a PR3, goto http://www.youtube.com - it's a PR8. There is a difference with \ without www so this is a bit of a wasted thread imo.
