Google Pages - High Rankings and PR out of the blue?!

At the end of February I wrote a post on Google Page Creator - just when Google released it. Well, 2 months later and a bit (today) I searched for my full name [Max Chirkov], just out of curiosity, and was very surprised to see my Google page ranking #2 just right below this site. Even more surprising is Google PageRank 4 for that page even though Google doesn't show any links pointing to it. I found a couple of links (on Yahoo) from this blog pointing there, but that's it. BTW, it also ranks #3 in Yahoo and #1 in MSN. I'm just wandering, how beneficial these pages can be in business and how exactly utilize them. Here is a little experiment, let's call it [Myrtle Beach Real Estate] - we'll see how it goes. Would be great to hear any ideas? Please feel free to comment.
