See http://blog.google.org/2008/03/introducing-rechargeit-blog_20.html

The new blog is at http://rechargeit.blogspot.com/.

I wonder when Google is finally going to move over to using google.com/org for blogs (other than the main google.org blog)?

this other blog has been launched some hours ago: http://adwordsagency.blogspot.com/
