Show Related Posts with the LinkWithin Widget

I'm totally digging the LinkWithin widget that points readers to related posts for each entry. Here's a video:

Text instructions:

1. Go to http://www.linkwithin.com/
2. Fill out the form in the lower right and click Get Widget. A page of instructions displays.
3. Click on Install Widget. Youu'll then be sent into TypePad to choose the blog you want to add the widget to.
4. Check the blog you want to add the widget to and click Add Widget.
5. Within an hour, LinkWithin will have indexed and your blog and started adding suggested reading for each post.
