It seems that a Google Page Rank Update is underway that started yesterday in the afternoon. Verified further by checking Technorati and finding some bloggers noticing that a 3rd Google PR update for 2007 is ongoing.
Well in a few more days we can actually conclude if it is a full fledged PR update that is happening, when we see that the changes in the Google Toolbar are permanent, either way, Good Luck to everybody and May Your Page Rank be High 😀
