If you're one who obsesses over Google PageRank scores (you shouldn't, but people do), you'll be happy to know that the little PageRank meter in the Google Toolbar is now showing new scores for pages for the first time in many moons.
Bear in mind that the PR scores used as ONE part of the Google ranking algorithm may have been updated before this within the algorithm itself, but now the toolbar is likely playing catch-up. Or not. It's another reason why you shouldn't freak about it.
Barry Schwartz gives a little background here: PageRank Update Taking Place. Aaron Wall here: Google PageRank: Toolbar Update. Nick W dissects who should get first dibs on spotting the update and a tip to force your toolbar to see it: PR Update - Confirmed.
