Youtube has made a couple of interesting changes for some reason or other. First, their "sites linking to this video" section is now loaded via Javascript; those links are no longer embedded in the page. Despite the fact that those HTML links had nofollow tags, apparently some people were using them to obtain juice.

And, they've also now added nofollow tags to the videos and favorites on profile pages, as illustrated below. As previously indicated, the salmon-colored links indicate a nofollow tag.

Just keeping you updated on YT's gradual transition from an independent company to a Google playground. Oh, and thanks again to all those bloggers who supported the anti-web nofollow because they thought it was what it was presented as. See also "We're all going to regret giving Youtube so many links".
