The recent PR update a few days back again takes the same route which the previous updates have done. i.e. Diminishing the value of Google Toolbar PR in SERP's. I even read an article by Matt Cutts which says having a low PR now has a higher chance of Google SERP's which seems quite arguable.

During this update several of the directory sites have lost google TPR and I am specifically using the term Google Toolbar Page Rank bcos now TPR is a lot different from the actual PR.

So whats the Google Gameplan? Why is Google doing this? Does it want to fool SEO firms ? Whats the logic behind this attuitude of Google? 

The answer is very simple:

Giving better results to users who search for a specific keyterm. Better results means better quality sites with the best suitable content for the user.

 Now what has changed? Whats changes has been made to the Google algo? Time to explore !!
