I noticed a surprising Google Toolbar update in currently in progress, one of my new websites Rooms in St Louis was only launched last month and now has a Pr3. There has been fluctuation on my other websites as well with mostly upwards PR improvement.
This is surprising as the last update was only a few weeks ago and they usually only occur every quarter, i wonder is Google is thinking of having a more frequent update process. Dosent really matter that much ofcourse as high PR does not mean high rankings (i have a pr2 website at no2 for its main keyword). But it is still nice to see that green bar moving to the right!
