Just a little FYI: Gravatars are now available in OSX 10.5 to add to any of your contacts. This is hopefully the first of many forays into other parts of the world of information that exists outside and throughout the web. As I said earlier, I would love to have Gravatars working hand in hand with OpenID to integrate more and more services together so that all of us have to spend less time doing data entry and management just to stay in touch with the people we know.  I have a post coming soon about a really exciting new project that may solve a lot of my gripes about the social networking world, so this will continue to be a theme around here.
