Yesterday, I participated in a Google Webmaster Hangout on Webmaster Central Office Hours. It is basically where a Googler answers your webmaster and SEO related questions.
I joined one yesterday that Google's John Mueller was nice enough to record and make available on YouTube for everyone else to see. It was live on his Google+ page and is also available on YouTube.
Here is the video from yesterday, my favorite part is about 10 minutes and 10 second in where I asked him what is the purpose of sending out notifications to ignore links when those links have no impact on your site? I love his expression when I asked that.
He also posted a video on July 20th:
I am incredibly grateful that Google puts these together.
