You thought Gravatar Profiles were cool? Wait until you see them on your WordPress.com blog.

Today dawns a new era in Gravatar awesomeness: Gravatar Hovercards. It’s now easy to find out about who is behind your favorite comments simply by moving your mouse.  This new feature is now enabled by default across WordPress.com.

What’s a Hovercard?

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.

As a commenter, Hovercards offer a great way to show your Internet presence and help people find your own blog. As a blogger, you can quickly check out who’s commenting on your blog, and have an easier time connecting with them.

How to use and see Hovercards

You can see other people’s Hovercards by moving your mouse over their Gravatar picture in comments on any WordPress.com blog, and after a moment the Hovercard will appear. The information shown is taken directly from the person’s Gravatar profile. The more info in the profile, the more we show in the Hovercard.

This can help you when moderating comments, as Hovercards will appear not only on blogs, but inside your blog dashboard as well.

If it’s not something you want for your blog, you can turn Hovercards off for your blog by going to Settings, Discussions, Avatars.

If you haven’t set up your Gravatar Profile yet, just log in to Gravatar.com using your WordPress.com username and password and fill out your details or read these instructions first. If you don’t have a WordPress.com account yet, you can sign up for Gravatar here.
