WordPress.com have announced they are upping your Gravatar Profile to a new level of awesomeness with Gravatar Hovercards. It’s now easy to find out about who is behind your favorite comments on WordPress.com simply by moving your mouse over their Gravatar. This new feature is enabled by default across WordPress.com.
Gravatar Hovercards show information about a person: name, bio, pictures, and their contact info at other services they use on the web like Twitter, Facebook or LinkedIn.
