Gravatars are popular among blogs and forums as a unique way to show your identity across the web. Whenever you wrote a comment on a blog, or sent an email – the administrator of that website could choose to use your details to display the picture that is associated with that specific email address.
Recently, Gravatar released its first step in bringing a whole lot more context and personality to your online presence. Every gravatar now supports the addition of full profile information against it. This new feature enables you to upload your favorite images to your profile.
Apart from that, you can verify your ownership of other online profiles and services like Digg, flickr, Facebook etc., and what you choose to share in your profile will be available for everyone.
Gravatar now sports some interesting features on new profiles:
You can make a gallery of your favorite images, add different contact methods, and link your other social network profiles to your Gravatar account. Every linked account is verified so you know it’s not an impostor.
As of now, you will only be able to view your own profile at Gravatar.com. If you remove all information from your profile, then other people will only be able to see your Gravatar.
