I'm wondering if they updated across the board or if it was just domains that have changed their names. I changed this blog's domain URL 3 months ago. Of course, that dropped my Google rank to zero. Now this blog has a PR of three. It may be that low because it is still "young" as far as domain names go. I totally expected a PR of 5, but oh well. Next time I hope.
Please let me know if you have an inside scoop.
