MyBlogLog users can easily relate to Google Friend Connect. You add a widget to your blog and visitors can join your site via their Google, Yahoo, AIM or OpenID account.

Once they join, their picture will show up in the Friend Connect badge. They can also explore profiles of other members or even grow their social network from your site itself by adding other site members as their friends. Pretty interesting.
