Google Launch YouTube Channel for Webmaster Tools

The Google Webmaster Tools channel on YouTube contains 5 new video tutorials for webmasters, including subjects such as submitting reconsideration requests and setting a geographic target for your site.

The new additions add to the pre-existing video presentations by Google support engineers which cover canonical link elements, image search and my favourite 'preventing virtual blight' in which Matt Cutts talks about how tactics such as 'no-follow' links can deter spammers from blighting your website.
