Google's Official List of all the Cosmic Panda changes to Google Search

They posted this awhile back but I thought it was worth directing people to this blog article where Google engineer Matt Cutts lists all the Cosmic Panda changes made to Google Search.

The post is relevant to Google Search but I wouldn't doubt if some of these algorithms were also applied to Youtube's Search functions.

I also came across this blog article that talks about how to adapt to the changes. It's directed at websites but since most of us need to rely on website traffic to obtain views to our videos, it's worth checking out.
