Not too long ago, a client at work was wondering what kind of options they could have for showing buddy icons in their blog comments. I looked around, but didn't really like any of the default plug-ins. Well, one struck my interest a bit, but the client wasn't looking for a third-party solution. What I found was Gravatar, a website that wants to host a visual identifier for you to be used anywhere online. It's a simple concept, but I was of course worried with setting up and managing another service, another plugin for my software, etc.
