Webmasters might have noticed that the big G Google has recently updated and rolled out their PR status and gave fresh ranking update on their corresponding website last week. PR update is confirmed by Matt Cuts head of the web spam team from Google who tweeted the confirmation.
Some sites PR went down and some went up. Luckily for me all went up. This blog went from PR2 to PR3 and two of my sites went from PR0 to PR3, most factored from the link development effort I made the past few months. So keep on building those links and add more quality content to your post. Next update update may take place after couple of months again.
