Youtube and Google+ Embedded Posts
If you embed Youtube videos on your web site you might want to take second look at the Google+ Embedded Post feature:
Instead of using a direct Youtube embed try creating a Google+ post that includes the video and your commentary. Embed that post on your site by following the instructions linked above.
People can still play the video in the page, but now they can also +1, Follow, and Reply to it. This engagement will make your conversation stand out in the new Youtube.com comments section.
