Over Christmas and the holidays, we reported early signs of a Toolbar PageRank Update. Those reports have now been confirmed by Google's Matt Cutts via Twitter. Matt said about 6 hours ago:
Yes, Google updated our toolbar PageRank values today. Consider this the confirmation.
You can then see other Googler's like JohnMu, "liking this" on Matt's FriendFeed page.
Of course, we have a whole new slew of PageRank update threads and posts now. They include:
The folks over at the brand new Google Webmaster Help section are happy to see their new forum reach a PageRank of 7, in a matter of just weeks.
So there you have it, as expected, the Toolbar PageRank update has been confirmed.
