Google has a page rank of -1!

I was trying to check the page rank of my blog (without having to install the pesky Google toolbar) and guess what I got? The result is laughable... I got this from whatsmypagerank.com in case you are wondering. Who's kidding who? :P PS.: And yes, I did try several variations like google, google.com, www.google.com . PPS.: To be fair, the "-1" might mean that the page rank is unavailable - possibly because Google has "banned" this site from bombarding it with page rank requests. Beats me but this website certainly needs to have a domain name change.
