Just checked a sample list of 100 domains and none have changed in PR. With Google, anything is possible though. Instead of full exports, they may be releasing updated PR at a snails pace just to add more confusion.
I have long thought that Google regretted letting us see pagerank values. It just makes certain sites targets for spam. I think they will remove it totally and we will just have to get on with our lives.
I will say that it is curious that we are still experiencing these changes in PR, regardless of the reason or direction, given what Google has said regarding the pipeline being broken.
I don't know the in's and out's of their pipeline. I think I can accept that manual penalties could be implemented and affect PR without a full on update/push, but a brand new site jumping from n/a to 2 seems to indicate that something is still functioning here in some capacity.
Maybe the pipeline they mention only comes into play on the full PR updates for all sites and not smaller updates and manual actions? So we could continue to see movement in PR for these reasons?
Note that we're referring to TBPR (Toolbar Page Rank) here. Matt made it clear that Google continues to keep PageRank updated internally... it's just the Toolbar that isn't changing.
I got the sense, from Matt's statement at PubCon, that... for reasons viral's post suggests... Google might be rethinking the question of whether to show TBPR at all. Not anything Matt said specifically... just the lack of importance Google seems to be attaching to the display.
That said, I am seeing enough reports that Google is using it TBPR selectively to suggest Google also finds the display useful in some cases.
So are we basically saying that everything that keeps the TBPR data and does the math is working just fine, but it's just that Google is not bothering to fix whatever is causing the display of TBPR to show the old results?
Whereas other browser plugins/extensions are using that same data and properly showing the updated new results?
Half right. I think we are saying that even though the PageRank continues to change, those changes are not exported to display; whether Google tool bar PR or any other PR checker/plugins. I have not seen any reports of some toolbar plugins/extensions working while not working on others. I think you may be confusing this with the fact that Google has removed the PR tool bar option from every browser apart from IE?
In some rare cases, we have seen sites jump to immediate PR but these normally are sites that have existing link profile and have therefore not lost their PR in the first place. We have two examples of this.
