Both of these are provided by http://feedjit.com/
The first, is working really well on my iPod Blog. It's Feedjit's Collabarative Filter. A "Visitors Who Liked This Page Also Like..." widget. It's just a piece of javascript that goes in to your template and suggests other articles/posts ON YOUR SITE that may be of interest to the reader.
Now, because it's javascript it won't be of any help getting pages indexed by search engines, but visitors to your site will use it. They certainly on www.doipod.com.
You can see it in action at http://www.doipod.com/ipod/2008/03/a-girls-perspec.html
TypePad users can add it via the Typepad Widget page here. Others can grab it from http://feedjit.com/
The second is more for your own use. It's feedjit's Live Traffic Map. You can see it action at the bottom of www.doipod.com. It provide you (and other interested) with a map showing where you visitors came from and what they viewed. It also shows the popularity of pages of your site. Interesting stuff.
Typepad users can grab it here, while others can get it from http://feedjit.com/
