This is a really cool widget. Several popular blogs incorporate this neat little tool which keeps a snapshot of the latest visitors to your blog. Not only that but the users that can build a profile of blogs for his/hers favorite topics - a great way to discover new good content in this blazing fast web world.

This is one of my favorite widgets! Once you install this widget into your blog you can see who visits your site. Because the widget shows your picture everytime you view another blog with this widget it also helps drive traffic back to your own blog.
