Hi,
On the 'Viper chill' blog (some may of heard of this blog) he talks about interlinking content in an attempt to build up link juice to get more from the content and pass more PR to the target website.
Here is the link to the post, a few scrolls down and your see a diagram.

I have also attached the image to this post, so we can discuss in more detail by referencing to it.
Now this guy knows what his talking about, lots of big players back him up, but does this method actually work better then having one link from each article pointing to the target website?
If an article links to another article surely the PR flows into other links on the page as well as your own down grading the power of it?
If the answer is yes, would this work for guest blogging?
