When I uploaded my first YouTube video, I got some comments and I wanted to reflect them on my blog where I was also displaying my video. Traffic to my blog is important as well as is the permanent record in my database of these comments. However, I need a two way solution. If someone comments on the video on my blog I want those to appear on my YouTube account. I need to Sync comments between my blog and Youtube.

The Genki YouTube Comments plug-in works well (I use it on my site now.) for pulling comments from YouTube to a WordPress blog:

However, this is only half the sync. I have yet to find a solution for when someone comments on a WordPress blog that the comment is then sync’d over to YouTube. If someone knows a solution for this then please share.
