Page Rank Update in Progress

It is being reported from several sources including Courtney Tuttle that there is a potential Page Rank in progress.  

If you try using a Page Rank prediction or verification service that gathers data from multiple data centers, you may find that it won’t work.  This update will primarily be displayed in the Google Toolbar, if you are using it.  

Despite the popularity of using Page Rank as a determining factor of a site’s value (and advertising prices), it should never be used solely to determine a blog’s popularity.  Practice good blogging and you’ll see more benefits than simply an increase in your rank.

Has your Page Rank increased or decreased?  Does Page Rank matter to you?  Generally, the blogs that have mentioned the update have seen a 1-3 rank increase.
