Can anyone explain this?

This has happened to my sites several times before. Although I don't have an explanation for the anomaly, what I have seen when this happens is that your homepage PR will eventually catch up with internal page PRs...most probably on the next PR update. I don't think this is something to be overly concerned about. -- This message may have been cut off and the rest will only be shown to members. To become a member, click here --

PR5 -> PR1
God... google is killing me. I'm of the firm opinion their search is broken, and has been broken for months.
Several searches I have run into for recent events and such have returned virtually NOTHING on google, but tons on yahoo and msn. Google is broken, and continues to be broken, tired of it.. they need to fix it or just redirect to msn and get out of the way. -- This message may have been cut off and the rest will only be shown to members.

PONTING Can you tell me which searches didn't return anything on Google, but tons on Yahoo and MSN? Sounds interesting...I would love to bench mark this! my main sites ticketnest went 4->5, but my experimental site graphicdog.com went 0->6 .

I had a couple sites do that to me at bigdaddy pr update, my homepages would stay at the pr or lack there of whereas my innerpages where all 5's and 6's.On all sites the pages that did not change pr where indexed prior to bigdaddy, and the high pr inner pages where indexed in the bigdaddy datacenters for their first index in google. It goes to show a couple of things, one toolbar pr means jack, cause if my homepage pr of 3 can pass pr 5's to most pages and 4's to other I guarantee you Google doesn't treat my homepage like a pr 3 and more like a 5 + internally.Also somethings wierd with pages prior to BD.
Also your toolbar keeps reverting back because some of the DC's haven't been updated yet just like the big daddy pr update, and with what Matt Cutts is Saying, it will take a while for it to finalize. -- This message may have been cut off and the rest will only be shown to members.

Dont get me started on this, I been sweating BLOOD
Basically my sites have jumped all over the place. One day a pr5, one day a pr6 one day a pr4 then back to 6
Does anyone know if its finished as everytime I am login, I am scared that a bunch of customers (I sell links) are going to burn me at the stake as my pr has dropped -- This message may have been cut off and the rest will only be shown to members. To become a member, click here --

Don't say I didn't tell you all, When this update started, I said that this will be a screwy update, but oh no, everyone's celebrating with their PR6's and PR7's - selling links at a PR that wasn't even showing on the toolbar!
