Over the weekend there has been speculation that there will be a pagerank update by Google pretty soon. Now I have definitive proof that the update is in progress
Just found out that a google pagerank is in progress. The forum on mywalkin has gone to PR3 from a PR0. The IT blog retains its PR0 status. Surprisingly the main website mywalkin.com has gone down to zero 
Hoping that this is something abnormal as the pagerank update is in progress.
On a happier note my brand new second hand mobile site has got a PR1. Binaryday is yet to regain the pagerank that it had lost in the domain name goof up a month back. Just hoping that it shall be restored by the time this update is over.
Let me know if your PR has changed recently.
