It appears that there is a Google Toolbar PageRank update underway. For anyone not familiar with this topic, the value of the toolbar-displayed PageRank is often argued. A recent discussion which helps to clear up the original poster's misconceptions about PageRank can be found at Cre8asite Forums.

The topic was also started at Search Engine Roundtable Forums today, and feel free to link to further discussions in the comments below.
