Go figure, I post an update about my Whypark site, and Google decides to update page ranks today as well. The Whypark test site I'm using made PR3, and comparison my blog only hit PR2. I personally don't care either way, but many ad networks only work with sites with a minimum page rank value still so have a parked domain with page rank just means more revenue options.
In my previous post I also mentioned that I was only getting about 1 visitor a month to the Whypark site. This just goes to show you that page rank value has no value or connection to actual website traffic.
