I see avatar feature in version 3. Very good and nice feature. And It could be better if we have public profile too. For example when a visitor or users click on the feedback icon ( letter icon to send email ) in the blog they can see the publisher profile too ( His/her avatar, name, links, IDs and ... ). Another example is when a user sends comment, his/her avatar would appears at the top of his/her comment and if somebody click on his/her avatar, could see his/her public profile... ;)
