I also tested my blogs. Haha. My website's pagerank already go down. Not enough to get many links from Alexa, Digg, and others. Because I not always write my blogs since I am busy to work with my projects.
Now, they called "Google Page Rank Checker" , my page now is Rank 3 only. You can test your site and go visit at http://pagerank.chromefans.org/pagerank-checker/ if you want to know ya!
