I'm not entirely sure how this works.
I'm assuming that it starts with the most popular video,
And then selects a few of the related videos and shows those surrounding it.
A few things I'd like to see done with this.
It's really confusing once you get more than a few generations of videos.
It'd be nice if they were connected to their parent video somehow.
I'd be really interested to see this done with Wikipedia.
Excpet instead of just the top 8 links,
Have every link displayed in the article.
Back links to recurring pages would be nice too.
