What… you’ve never heard of a Gravatar?  For shame… with Gravatar’s you can link your email address (any of em) to a ‘globably recognized avatar’ (or image) so that when you comment on a blog, it will recognize your gravatar linked email address and show your avatar next to your post.  How keenoneat!  So go git yourself one, and spice up the comments more with your freakishly cool avatars!
