Google released 2 new features which allow any blogger with access to the HTML template of their site to embed 2 badges = communication channels for direct contact with readers:

- Free phone calls via Grand Central VOIP service (WebCall Button). The button also allows you to post voice mail to your blog which replaces the now defunct AudioBlogger feature.

-

Chat via Google chat (Chatback badge)
