#1 ranking - zero content, what gives

I own a domain that I have left dormant for awhile (I have had it for approx 1 year). The HP url has a PR3. 1 week ago I decided to run a SEO test for fun. I started to work on a mini site about Chocolate Labs. I created one page for history of the breed. I also set up a title and meta tags on the PR3 page I had lying around. I did not link to the history page, It was literally a blank page with only meta tags and title, thats it.

Go to yahoo and search for
history of chocolate labs
I am #1. Look at the cached version! Yahoo is looney. They put me at #1 with zero content! Granted it is not a tough term to rank for, but it came back with 100K+ matches.

There is a link on that page now to the blog I started today. This ranking does not have to do with the blog at all (which the cache version attests to).

What does this tell us?

Tells us that there is no real competition of any substance for those keywords.

If you look at the sites around you it will show you that.

I saw a few on freespace that looked like old ladys had built.

Yeah I guess you are right, which is not suprising. Still seems odd that zero content can get you #1 for anything over anyone with any sort of content.
