I’ve added a few new comment features to go with the new design. The first is the use of gravatars, short for Globally Recognized Avatars. If you link one of these images to your email address it will show up next to your comments here and at thousands of other sites that use them. The service is free and available at gravatar.com.
The comment form now gives you the option to verify your identity with an OpenID. Information on creating an OpenID is available here, along with reasons why you may want to have one (you already do if you’re on Blogger, WordPress.com, Flickr, or a variety of other services). The OpenID logo will appear next to verified comments and behind commenters’ name in the sidebar.
Comments now also have a reply-to feature. If you’re replying to a specific comment in a thread, just click on the arrow beneath it to automatically link to that comment and the author’s name. For example, if you want to reply to Bob, clicking on the arrow will start the comment form with “@Bob:” and a link to his comment. This is totally optional, but it can make longer threads easier to follow.
Finally, I’ve added a “Share/Save” button to the bottom of every post. Clicking on this will open a menu for emailing posts or sharing them on services like Facebook, Digg, and Twitter. When you read a post you like, I appreciate your help sharing it with a larger audience.
