What is the best way to keep up with googles changes? They Google Search Central blog?

I just got done reading probably about 50 of Google's documents on how they rank and how their search works. My head is spinning but I do feel a lot more educated now. I'm sure a lot of you have already read those documents too on everything from how search works, indexing to crawling to spambrain to feature snippets to helpful content algorithm and everything else. I am enlightened by their search quality rater program and didn't know that they actually hire these people to rate their algorithm. What's the best way to keep up it all of its changes? Do we just keep reading all the blog posts on Google Search Central?
